A macuahuitl, a
type of macana, is a wooden sword with obsidian blades. The name is
derived from the Nahuatl language. Its sides are embedded with prismatic
blades traditionally made from obsidian, famous for producing an edge
far sharper than even high-quality steel razor blades. It was a common
weapon used by the Aztec military forces and other cultures of central
Mexico. It was described during the 16th-century Spanish conquest of the
region.
He
joined the Army Air Force in 1945 and was qualified as a B-17 “Flying
Fortress” Radio Operator/Aerial Gunner, serving in Europe at the end of
WWII. He was awarded the American Campaign Medal, WWII Victory Medal and
German Occupation Medal. James Best (born Jewel Franklin Guy;
July 26, 1926 – April 6, 2015) was an American actor, who in six
decades of television is best known for his starring role as bumbling
Sheriff Rosco P. Coltrane in the CBS television series The Dukes of Hazzard. He also worked as an acting coach, artist, college professor, and musician.
While comprising a group of Germanic tribes from continental
Europe, the Anglo-Saxons established themselves in Great Britain from
the 5th century. This consequent Anglo-Saxon epoch (from roughly 449 –
1066 AD) led to the creation of the English nation and the resurgence of
Christianity in Britain. And even beyond culture and religion, one of
the lasting legacies of these Germanic people is their contribution to
the ambit of language – what we know today as Old English. However in
this article we have decided to explore one of the lesser known avenues
relating to the Anglo-Saxons, and it pertains to their incredible
military that bridged the gap between the ancient ‘barbarian’ Germans
and the ordered medieval armies. So without further ado, let us take a
gander at ten fascinating things you should know about the Anglo-Saxon
warriors.
1) The Roman influence?
Illustration by Angus Mcbride
While the diminishing of Roman imperial rule set the tone for
Anglo-Saxon arrivals at the shores of the British islands (circa 5th
century AD), it should be noted that the late Roman Empire already
followed an ‘inclusive’ military doctrine that allowed the employment of
auxiliary units. By 4th century, in the northern frontier, these
auxiliary units were often composed of entire Germanic sub-tribes, who
were settled as foederati (allied troops) in marches, buffer
zones and areas of conflict. During the same time-period, the Romans (or
Romano-British) had already begun to set up coastal defenses to protect
their shores from the forays of the independent Anglo-Saxon tribes.
The ancient city of Akragas (or Ἀκράγας) in Sicily was one of the major Greek-populated settlements of Magna Graecia,
during what is termed as the golden age of Greek city-states (circa 5th
century BC). The city was originally founded in early 6th century by
Greek colonists from Gela (in Sicily), and by the turn of the century it
possibly had a population of more than 100,000 people. In fact, even
after numerous political and military upheavals during the Punic Wars,
the city managed to regain its prosperity, so much so that its
inhabitants (the city being renamed Agrigentum) were granted Roman citizenship after the death of Julius Caesar in 44 BC.
Last month we showcased the (what if) 3D reconstruction of the Solomon’s Temple
in accordance to its Biblical measurements. Now beyond its religious
status as the grand First Jewish Temple built on the Temple Mount,
Solomon’s Temple is also known for its housing of the fabled Ark of the
Covenant. This naturally brings us the million-dollar question – what
exactly was the Ark of the Covenant? Well as literary sources mention,
the legendary artifact was possibly a gold-plated chest that stored the
sacred tablets containing the original Ten Commandments. But as every
Indiana Jones fan worth his salt would know, the Ark is elusive (or
perhaps even ‘illusory’) – and as such is still lost to the researchers
of our modern age. But an ancient Hebrew text translated in 2013, might
provide some (possibly fancy) insights into the whereabouts and status
of this puzzling artifact, along with the other treasures of King
Solomon – who was said to be the richest man of his time in Biblical
sources.
From the historical perspective many scholars believe that music
played an integral role in the lives of ordinary ancient Greeks, given
its role in most social occasions – ranging from religious rites,
funerals to theater and public recitation of ballads and epic-poetry.
Both archaeological and literary evidences rather bolster such a theory
that points to the crucial nature of music in ancient Greece. In fact,
the Greeks attributed the ‘creativity’ of musical compositions to divine
entities, and as such etymologically the very word ‘music’ is derived
from ‘Muses‘, the personifications of knowledge and art who
were the nine daughters of Zeus and Mnemosyne. Interestingly, Mnemosyne
herself was the personification of memory, and was also one of the
Titans, the children of Uranus the Sky and Gaia the Earth.
Furthermore when it came to the ancient Greek musical instruments, the musicians had a penchant for lyres (and kithara), aulos pipes and syrinx, and even the hydraulis
– a setup that was the precursor to the modern organ. And with the aid
of the flurry of archaeological and literary evidences of vocal
notations and musical ratios, combined with the identification of these
instruments, researchers have been able to recreate precise renditions
of ancient Greek music. For example, Dr David Creese,
Head of Classics & Ancient History at the University of Newcastle,
has devised the following reconstruction of a musical piece that was
etched on the ‘Seikilos epitaph’ dating from 1st century AD –
Now in case you are interested, the ‘song’ that was recreated by Dr
David Creese is actually the world’s oldest known complete song.
Inscribed on the Seikilos epitaph, the ancient Greek characters on the
slab allude to the piece’s Hellenistic Ionic origin. Interestingly, the
completeness of its composition is partly due its short nature. To that
end, the lyrics has been roughly translated to English, excluding the
musical notation –
While you live, shine
have no grief at all
life exists only for a short while
and time demands its toll.
This lyrical part is also accompanied by a poignant etching that
takes narrative of the epitaph itself – “I am a tombstone, an image.
Seikilos placed me here as an everlasting sign of deathless
remembrance.” In any case, as opposed to the Hurrian Hymns (the oldest
known song in the world), the Greek composition on the Seikilos epitaph
is complete – and thus is less open to interpretation. Simply put, there
is more chance of hearing the originally ‘intended’ rendition of this
Ionic song, even when recreated in our modern times. So if interested,
you can check out this vocal rendition of the enchanting ‘Song of
Seikilos’ – the oldest known complete song in the world –
And in case you are in mood for something more jovial, take a gander at
the modern guitar-fueled cover of the ‘Song of Seikilos’, sung and
played by famous internet teacher Hank Green –
The Greek word for military equipment roughly translates to hopla,
and thus a hoplite simply pertained to the ancient Greek version of the
‘man at arms’ or ‘armored man’. But as opposed to their late medieval
counterparts, the ancient hoplites were first and foremost
citizen-soldiers. Simply put, these conscripted men were expected to
take part in battles to safeguard their own interests, freedoms and
farms, in contrast to viewing military as a contractual well-paying
career. And while the ‘classic’ well-armored and trained Greek soldier
was ultimately eclipsed by the tactical Macedonian phalanx in late 4th
century BC, hoplites (and their predecessors) had dominated the
Mediterranean battlefields for almost three centuries before that.
On the other cultural spectrum, the development of ancient Greek art
was rather mirrored by the pottery designs that were made between the
time-fame of 1000 – 400 BC. Continuing the artistic legacy of the
earlier Minoan pottery and Mycenaean pottery, the vase painting in the
late Archaic Age (620 to 480 BC) mainly comprised the so-termed ‘black
figure’. As Mark Cartwright wrote (for Ancient Encyclopedia) in regard to the predominance of black figures during the aforementioned period –
The unique legacy left behind by late Marcel Mazliah is something
to boast about when it comes to a historical scope. Over the years, the
electric company worker had made a personal collection of priceless
artifacts (with one of the items being around 3,500-years old) that were
salvaged from the Mediterranean Sea bordering Israel. And fortuitously,
his family has now decided to hand over the incredible treasure trove
to the Israel Antiquities Authority (IAA), which would earn them a good
citizen award from the state. But beyond ownership and recognition, one
particular artifact from the collection stands out – and it entails an
actual Crusader-era hand grenade that rather showcases its medieval
brand of fine craftsmanship.
From the perspective of etymology, the term ‘grenade’ was most probably derived from Old French ‘pomegranate’ (possibly influenced by Spanish granada)
circa 1590 AD, since the fruit resembles the fragmented-form of the
weapon. As for the historical side of affairs, grenades in their
rudimentary designs were probably used in the 8th century AD Eastern
Roman armies, with Greek Fire concoctions sometimes being stashed inside
pots and jars, to be thrown at enemies.

Greek Fire
in itself is said to be originally created by a Syrian Engineer named
Callinicus (who was a refugee from Maalbek). The technology was sort of a
precursor to napalm, and it entailed vicious ‘liquid fire’ that
continued to burn even while floating in water. In fact, some writers
have gone on to explain how the viciously efficient Greek Fire could
only be mitigated by extinguishing it with sand, strong vinegar or old
urine.
As for the hand grenade in question here, the embellished metal-made
bomb-like item probably harks back to the period circa 13th century AD,
thus coinciding with the time-frame of the Crusaders, Ayyubids and early
Mamluks. The military forces of this time possibly used some variation
of an inflammable substance, including a combination of materials like
naphtha, pitch (obtained from coal tar), sulfur and resin – for their
grenades. On the other hand, a few scholars believe that as opposed to
chemical warfare, these ‘grenades’ only had ornamental purposes for
storing perfume.

In any case, archaeologists from the IAA were pleasantly surprised by
a slew of other metal objects that were stashed by Mazliah. According
to his family, the electric company worker got hold of the artifacts
from under the sea, as a result of numerous ancient and medieval
shipwrecks that dot the Israeli coast. Ayala Lester, a curator with the
IAA, stated –
The finds include a toggle pin and the head of a knife
from the Middle Bronze Age from more than 3,500 years ago [see above].
The other items, among them, two mortars and two pestles, fragments of
candlesticks, and so on, date to the Fatimid period. The items were
apparently manufactured in Syria and were brought to Israel.
Lastly beyond the scope of the treasure trove accumulated by Mazliah,
the occurrence of shipwrecks around the coastal regions of Levant could
be attested by a fascinating find in May of this year. Touted to be the
largest hoard of marine-based objects
in the last 30 years in Israel, IAA announced that the treasure stash
contained both bronze statues and coins, along with other assorted
stuff. And interestingly enough, the discovery was made quite by chance
when two divers identified the remains of the ancient ship and reported
back to the authorities.

A 1700-year old limestone epitaph slightly bigger than an iPad
sheds light into the fusion of different religious entities prevalent in
early 3rd century AD ancient Egypt. Salvaged from a collection of Greek
and Coptic artifacts from University of Utah’s J. Willard Marriott
Library, this engraved object commemorates a woman named Helene. And
while she is identified (in the epitaph itself) as a Jewish woman,
Helene is also referred by a title that was usually associated with
Christian women in this late-antiquity time period of Egypt, thus
alluding to an inclusive societal scope.
The translation was made by BYU associate professor of ancient scripture Lincoln H. Blumell. The inscription reads like this –
The episodes of war and human conflicts are persistent when it
comes to the rich tapestry of history. And in such a vast ambit of
wanton destruction and death, there have been a few civilizations,
tribes and factions that had accepted warfare as an intrinsic part of
their culture. So without further ado, let us take a gander at ten of
the incredible warrior cultures from the ancient times that pushed forth
the ‘art of war’ (or rather the art of dealing with war) as an
extension of their social system.
Researchers from the Jerusalem-based Temple Mount Sifting Project
has accomplished quite a feat by restoring a unique architectural scope
of the once-monumental Second Jewish Temple. This fascinating ambit
mainly entails the richly decorated floor tiles that adorned the
porticoes on the Temple Mount. Simply put, these ancient specimens
probably played their decorative role along the courtyards of the huge
temple complex, corresponding to the period when King Herod ruled over
the Roman client realm of Judea (circa 37 – 4 BC). Now interestingly if
the project is assessed to be accurate, this would be the first time
that archaeologists had been able to successfully restore any element
from the Second Temple.
Researchers announced the discovery of a new (extinct) species of
pterosaur from the Patagonia region of South America. The discovery was
made from the cranial remains of a specimen that were found to be a
pretty well preserved condition, probably dated from the Early Jurassic
period (around 200 – 175 million years ago). Interestingly enough, the
new species was named as the Allkauren koi, from the native Tehuelche language – with ‘all’ roughly translating to ‘brain’ and ‘kauren’ meaning ‘ancient’.
The very name ‘Pterosaur’ comes from the Greek for ‘winged lizards’.
These astounding flying reptiles ruled the skies between the late
Triassic to the end of the Cretaceous Period; and quite unsurprisingly,
one of the largest known flying animals of all time – Quetzalcoatlus,
comes from this extinct clade. In terms of size, the larger variant of
Quetzalcoatlus’ is estimated to have had an incredible wingspan of over
36 ft. But interestingly this was just one end of the size spectrum,
with some Pterosaur specimens also showcasing the diminutive dimensions
of small sparrows.
Just
one of the amazing pictures uncovered from the mysterious rolls of film
by the Rescued Film Project. (Image captured from the vIdeo below)
The
Second World War is considered to be one of the most filmed and
photographed conflict in recorded history. There were photographers
attached to the armies, recording every battle. They filmed and
photographed destroyed cities, piles of bodies, scared and shaken
citizens and starving Holocaust survivors.
Recent studies show
that there were many individuals filming the conflict, but that most of
those films were either lost during the war or were not developed in the
years following.
Photographer Levi Bettwieser discovered an amazing set of rolls in 2014. He runs the ‘Rescued Film Project’, paying tribute to the unknown photographer who had created the film during the war.
The
Rescued Film Project is a short documentary about the processing of
these mysterious film rolls. The process itself was quite an
exhilarating experience for him, but when he developed and saw the
pictures, he was astonished by his discovery.
While
hiking an old mountain trail in Haukeli (on the border of Telemark
County, Norway), Goran Olsen was surprised to discover a 1250 year old
Viking sword among some rocks near the road when he sat down to
rest. The sword was in excellent condition, especially considering its
immense age.
The
sword was taken to Hordaland County Council, where local archaeologists
working for the council were elated to have the opportunity to study
such a beautiful artifact. County conservator Per Morten Ekerhovd said,
“It’s quite unusual to find remnants from the Viking age that are so
well-preserved. It might be used today if you sharpened the edge

(21 meters) at 225 knots (415 kilometers per hour). This ninth attack in
one day on U-848 was followed by another run by Lieutenant Taylor, who
destroyed the U-Boat with two depth charges. U-848, a Type IXd2 U-Boat,
was commissioned on February 20, 1943 under the command of
Korvettenkapitan Wilhelm Rollman (August 5, 1907 - November 5, 1943).
Haykaberd (or Çavuştepe in Turkish) is an archaeological
site in Van Province in Turkey’s Eastern Anatolia region, known for its
ancient 8th century BC fortifications and royal palace of the Urartian
kings. But this time around, beyond ramparts and walls, archaeologists
are interested in seeds. Originally discovered in 2014, from the
Çavuştepe Castle that was constructed by Urartian King Sarduri II (circa
8th century BC), these batches of wheat and sesame seeds are almost
2800-years old. And now the researchers are looking forth to resurrect
these ancient specimens inside a laboratory environment.
Professor Rafet Çavuşoğlu (Archaeology Department) from the Van Yüzüncü Yıl University, said –
Erwin
Rommel was undoubtedly one of the finest generals of the Second World
War, his strategic mind and patient approach led his men to victory
after victory early in the war. But, while his fame and glory came as a
General and Field Marshal, it was as a Lieutenant in the First World War
that he earned his greatest honor.
Life
in a Ghetto was the unfortunate fate of many Jewish citizens during the
Nazi Party’s reign over Germany and its many occupied territories.
Crammed into hastily built quarters, packed amongst other people and
families all forced to leave their homes, little about life in these
ghettos was desirable.
Yet in one ghetto, the Jewish residents
held within its walls refused to accept the terrible fate the Germans
planned for them. In 1942, Warsaw Ghetto decided to fight back against
the execution of its people, and the Warsaw Ghetto uprising became the
largest revolt of Jewish people to occur during World War II.
Unfortunately,
the uprising led to the total destruction of the ghetto and the deaths
of so many of its residents – but before its buildings burned and smoke
filled the streets, its people made history.
PetaPixel has a wonderful post by Michael Zhang
with rare photographs of Revolutionary War veterans who actually lived
long enough to have their photographs taken. It’s an amazing post, so
don’t miss it. Photography was invented in the 1820s
and 1830s, and the Revolutionary War ended decades before, in 1783.
This meant that most Revolutionary War veterans didn’t live long enough
to have their photographs taken. That being said, there were a few war
veterans who did live long enough to be immortalized in portraits. In 1864, a full 81 years after the
war ended, Reverend E. B. Hillard and two photographers went to New
England to interview and photograph the six men known to have survived.
All of the veterans were over 100 years old. These amazing photographs
were made into a book called The Last Men of the Revolution. This is a fascinating look into history that we’re lucky to have.

Panzerkampfwagen
VIII Maus (“Mouse”) was a German World War II super-heavy tank
completed in late 1944. It is the heaviest fully enclosed armored
fighting vehicle ever built. Only two hulls and one turret were
completed before the testing grounds were captured by the advancing
Soviet forces.
These two prototypes – one with, one without turret
– underwent trials in late 1944. The complete vehicle was 33 ft 6
inches long, 12 ft 2 inches wide, and 11.9 ft high. Weighing 188 metric
tons, the Maus’s main armament was the Krupp-designed 128 mm gun. This
128 mm gun was powerful enough to destroy all Allied armored fighting
vehicles then in service, some at ranges exceeding 3,800 yards.
What
would happen to your family should one of your siblings join a deadly
political beast? If you were a member of the Göring family in the first
half of the 1900s, you would find your entire family divided. This was
the situation between Albert and Hermann Göring, two brothers torn apart
by World War II. While one brother, Hermann, became a proud member of
the Nazi Party, the other, Albert, chose an entirely different
direction.
Truly
touching moments of humanity, ethics and morals are rather rare in
warfare. The Christmas Truce of WWI was an excellent example of such
humanity, as were the heroic actions of German Luftwaffe fighter pilot
Franz Stigler on December 20th, 1943. His actions got nine men home for Christmas.
Charlie
Brown of the USAAF was a Lt. flying his first mission as an aircraft
commander flying a B-17, “Ye Olde Pub” on a bombing run over Bremen.
Brown’s bomber occupied the especially dangerous left of the formation,
sometimes called the Purple Heart Corner. Bremen was defended by a large
contingent of fighters and well-manned flak guns. Two B-17s were
quickly struck by heavy flak, and many went down. Brown’s bomber was hit
at least once in the left wing. The crew had to shut down an engine
which took them out of the formation. Soon they were met by about eight
enemy fighters.
The B-17 was sometimes referred to as the flying
porcupine and Ye Olde Pub sure lived up to The name. the gunners took
out at least one of the fighters and as many as three, all on their own.
The remaining fighters were still able to take the fight to the bomber,
however, and bullets tore through Ye Olde Pub.
Many
heroes’ names line the pages of WWII history. Many of these men and
women were not recognized and known to the public during their lifetimes
– some were secret agents, some worked within underground resistance
groups, and some conducted their plans hidden in plain sight.
One
man in particular fought back from within the Nazi Party, reporting its
atrocities and plotting to bring them down from the inside. That man was
Edmund Glaise-Horstenau, a general within the Austrian military and
respected Nazi leader.
Though so many of his fellow Nazis
facilitated the concentration camps and various other horrors conducted
during the war, Glaise-Horstenau did not – he wanted the reign of terror
to end, even if he had to die to make this dream a reality.
The
south steps of the Confederate White House teeming with Southern
officers and soldiers. Freedwoman Mary Bowser, posing as a slave, often
spied here for the Union.
The
typical Southern officer’s opinion of African Americans was that they
were an inferior subhuman race, lacking in intelligence or cunning.
Their ignorance and subsequent disregard of the slaves in their midst
led to the most successful intelligence gathering of the Civil War.
The
black men and women that provided information to the Union did so at
extreme peril and risk that they would never outlive, even long after
the war was over. They did this gambling that the pay-off would be
winning the war and trusting that they would hopefully gain
their freedom. There would be no accolades or acknowledgment. Such
attention, even long after the South fell, would put them in danger of
retaliation from disgruntled former Confederates.
Great image here for the scale of the ‘flying crane’. sourceOK,
it looked ugly and strange but it worked – kind of. Made from parts
from various WWII warbirds the Hughes XH-17 “Flying Crane” was by far
,the most impressive of all rotor-craft in the early 1950s was a strange
monster designated XH-17. This was planned and taken through the design
process by Kellett, but hardware trials were transferred to Hughes
Aircraft at Culver City. Already the aircraft firm of billionaire Howard
Hughes had a reputation for being quite undeterred by the most
formidable development problems, and certainly the XH-17 made sense on
paper. In any case, it was part-funded by the USAF. It was a flying
crane, the specialized category pioneered by the German Fa 284 and
intended to lift cargo weighing up to 27,000 lb more than ten times as
much as any other rotorcraft of its day. To do so it had a radically new
form of lift power.

The
prototype was finished in 1949, ahead of schedule and one of the
reasons being that it was made from parts poached from WWII warbirds.
The XH-17 was a heavy-lift rotorcraft that was designed to lift loads
in excess of 15 metric tons.
To speed construction, parts of the
XH-17 were scavenged from other aircraft. The front wheels came from a
B-25 Mitchell and the rear wheels from a C-54 Skymaster. The fuel tank
was a bomb bay-mounted unit from a B-29 Superfortress. The cockpit was
from a Waco CG-15and the tail rotor from a Sikorsky H-19 was used for
yaw control.
In
the late 1940s, Hughes developed an interest in helicopters. In August
1947, helicopter manufacturer Kellett sold his design for the giant
XH-17 Sky Crane to Hughes, who commissioned the development of the XH-17
Flying Crane research vehicle. In 1948, the XH-17 began to take shape.
The giant helicopter was tested in Culver City, California over a
three-year period beginning in 1952. The XH-17 flew in 1953 at a gross
weight in excess of 50,000 pounds (23,000 kg). It still holds the record
for flying with the world’s largest rotor system. Only one unit was
built, since the aircraft was too cumbersome and inefficient to warrant
further development.
Engines: two GE J35 turbojets Weight fully loaded: 52,000 lb Cruising speed: 60 mph Range: 40 miles Number of seats: 2. sourceThe
propulsion system was unusual. Two General Electric J35 turbojet
engines were used, sending bleed air up through the rotor hub. The
blades were hollow, and the hot compressed air traveled through the
blades to tip jets where fuel was injected. In flight, the rotors spun
at a sedate 88 rpm. Since the rotor was driven at the tips rather than
the hub, little torque compensation was required.
The XH-17 employed an unusual gas-turbine and rotor-tip combustion combination to provide power to spin the gigantic rotors.
Thus, the XH-17 had a very small tail rotor compared to its main
rotor. This drive system was inefficient, limiting the test aircraft to a
range of only 40 miles. Finally, having received the Air Force serial
50-1842, the XH-17 was first flown by Gale Moore at Culver City on 23
October, 1952. That flight, however, had to be cut short after the XH-17
had been airborne for barely a minute as directional control forces
were excessive. While correction of this deficiency could be made
quickly, difficulties uncovered later in the trials required more time.
In particular, high vibratory stresses in the main rotor blades were
difficult to correct and the XH-17 was repeatedly grounded while
modifications were incorporated. The off and on test programme ended
when the rotor blades reached their design life in December 1955
writes aviastar.org
Hughes experimental helicopters XH-17 at the front XH-28 mock up at the rear. sourceBy
the end of the test program the XH-17 had proved its concept, that it
could fly, and that it could carry a considerable payload – exceeding
the original requirement. However it fell short, well short, of the Air
Force’s range requirement. Mainly due to its appalling fuel consumption,
and there was little which could be done to improve it.
In the
end it became a bit of an engineering cul-de-sac. One derivative, the
XH-28, an even larger version, was proposed. But it never got further
than a wooden mock-up. The sole XH-17 prototype was eventually scrapped,
and sadly nothing remains of this unusual giant except for photos and
some video footage.
Ground
tests began towards the very end of 1949, and immediately the sheer
size and complexity of the rotors, and their unusual powersource began
to throw up some issues for the engineers. However the project continued
to develop at a satisfactory pace. source
The giant rotors promised a huge lifting capacity, so they were attached to stilt-like legs and a box-like fuselage. source
Entry to the cockpit required a pair of tall ladders attached to the forward landing gear legs. source

The
prototype was finished in 1949, ahead of schedule and one of the
reasons being that it was made from parts poached from WWII warbirds.
The XH-17 was a heavy-lift rotorcraft that was designed to lift loads
in excess of 15 metric tons.
To speed construction, parts of the
XH-17 were scavenged from other aircraft. The front wheels came from a
B-25 Mitchell and the rear wheels from a C-54 Skymaster. The fuel tank
was a bomb bay-mounted unit from a B-29 Superfortress. The cockpit was
from a Waco CG-15and the tail rotor from a Sikorsky H-19 was used for
yaw control.
In
the late 1940s, Hughes developed an interest in helicopters. In August
1947, helicopter manufacturer Kellett sold his design for the giant
XH-17 Sky Crane to Hughes, who commissioned the development of the XH-17
Flying Crane research vehicle. In 1948, the XH-17 began to take shape.
The giant helicopter was tested in Culver City, California over a
three-year period beginning in 1952. The XH-17 flew in 1953 at a gross
weight in excess of 50,000 pounds (23,000 kg). It still holds the record
for flying with the world’s largest rotor system. Only one unit was
built, since the aircraft was too cumbersome and inefficient to warrant
further development.
Engines: two GE J35 turbojets Weight fully loaded: 52,000 lb Cruising speed: 60 mph Range: 40 miles Number of seats: 2. sourceThe
propulsion system was unusual. Two General Electric J35 turbojet
engines were used, sending bleed air up through the rotor hub. The
blades were hollow, and the hot compressed air traveled through the
blades to tip jets where fuel was injected. In flight, the rotors spun
at a sedate 88 rpm. Since the rotor was driven at the tips rather than
the hub, little torque compensation was required.
The XH-17 employed an unusual gas-turbine and rotor-tip combustion combination to provide power to spin the gigantic rotors.
Thus, the XH-17 had a very small tail rotor compared to its main
rotor. This drive system was inefficient, limiting the test aircraft to a
range of only 40 miles. Finally, having received the Air Force serial
50-1842, the XH-17 was first flown by Gale Moore at Culver City on 23
October, 1952. That flight, however, had to be cut short after the XH-17
had been airborne for barely a minute as directional control forces
were excessive. While correction of this deficiency could be made
quickly, difficulties uncovered later in the trials required more time.
In particular, high vibratory stresses in the main rotor blades were
difficult to correct and the XH-17 was repeatedly grounded while
modifications were incorporated. The off and on test programme ended
when the rotor blades reached their design life in December 1955

the end of the test program the XH-17 had proved its concept, that it
could fly, and that it could carry a considerable payload – exceeding
the original requirement. However it fell short, well short, of the Air
Force’s range requirement. Mainly due to its appalling fuel consumption,
and there was little which could be done to improve it.
In the
end it became a bit of an engineering cul-de-sac. One derivative, the
XH-28, an even larger version, was proposed. But it never got further
than a wooden mock-up. The sole XH-17 prototype was eventually scrapped,
and sadly nothing remains of this unusual giant except for photos and
some video footage.
Ground
tests began towards the very end of 1949, and immediately the sheer
size and complexity of the rotors, and their unusual powersource began
to throw up some issues for the engineers. However the project continued
to develop at a satisfactory pace. source
The giant rotors promised a huge lifting capacity, so they were attached to stilt-like legs and a box-like fuselage. source
Entry to the cockpit required a pair of tall ladders attached to the forward landing gear legs. source

As
the beginning of the war swept over Europe, with lightening speed,
Hitler felt invincible, at least for the first two years of the war. He
was known for his megalomaniac ambitions, but the most telling example
of his unrestrained hubris was endorsing the Landkreuzer P.1000, which
he nicknamed The Rat (Ratte).
It was supposed to be more than five
times heavier than its predecessor, Panzer VIII Maus, a super tank,
built in late 1944. About 1,000 metric tons was the predicted weight, 35
meters long, 11 meters high and 14 meters wide it was to be the biggest
land war machine ever created.
Sverd
i fjell (English: Swords in Rock) is a commemorative monument located
in the Hafrsfjord neighborhood of Madla, a borough of the city of
Stavanger in Rogaland county, Norway. They commemorate the historic
Battle of Hafrsfjord that took place there in the year 872, after which
King Harald Fair Hair united the three districts of Norway into one
kingdom. Harald Fairhair reigned from c. 872 to 930 and is today
recognized as the first King of Norway. The Three Swords (Sverd i Fjell) stand on the edge of Hafrsfjord, 6km from the center of Stavanger. The Sverd i fjell monument was put in place to celebrate an ancient battle. Source1 Source2
