Fort Knox: Gold Bullion Depository and Asset of the United States

Fun Facts About Fort Knox

• On June 28th, 1935, President Franklin Delano Roosevelt authorized construction of the federal bullion depository at Fort Knox, Kentucky
• Amount of present gold holdings: 147.3 million ounces.

• The only gold removed has been very small quantities used to test the purity of gold during regularly scheduled audits. Except for these samples, no gold has been transferred to or from the Depository for many years.

• The gold is held as an asset of the United States at book value of $42.22 per ounce.

• The Depository opened in 1937; the first gold was moved to the depository in January that year.

• Highest gold holdings this century: 649.6 million ounces (December 31, 1941).

• Size of a standard gold bar: 7 inches x 3 and 5/8 inches x 1 and 3/4 inches.

• Weight of a standard gold bar: approximately 400 ounces or 27.5 pounds.

• Construction of the depository:
  Building materials used included 16,000 cubic feet of granite, 4,200 cubic yards of concrete, 750 tons of reinforcing steel, and 670 tons of structural steel.
  The cost of construction was $560,000 and the building was completed in December 1936.

• In the past, the Depository has stored the Declaration of Independence, the U.S. Constitution, the Articles of Confederation, Lincoln’s Gettysburg address, three volumes of the Gutenberg Bible, and Lincoln’s second inaugural address.

• In addition to gold bullion, the Mint has stored valuable items for other government agencies. The Magna Carta was once stored there. The crown, sword, scepter, orb, and cape of St. Stephen, King of Hungary also were stored at the Depository, before being returned to the government of Hungary in 1978.

• The Depository is a classified facility. No visitors are permitted, and no exceptions are made.

Stonehenge: Ancient Monument, Astronomical Observatory or Something Else?

The Rock Pillars of Stonehenge

 

Fun Facts About Stonehenge

 

• Stonehenge is located on the Salisbury Plain in Wiltshire, England – about 137 kilometers Southwest of London.

• The origins of the name Stonehenge is taken from the combination of ‘stone’ and ‘henge’, a tribute to the biggest henge in Britain.

• Though there is no specific evidence about who built the Stonehenge. It is believed that Druids, Greeks, or Atlanteans might have built the Stonehenge.

• Stonehenge was constructed somewhere between 3100 – 1100 BCE.
• On September 21st, 1915, C.H. Chubb purchased Stonehenge for 6,600 pounds

• Stonehenge and its surroundings were added to the UNESCO’s list of World Heritage Sites in 1986 and is also legally protected by the Scheduled Ancient Monument.

• Stonehenge is owned by the Crown and managed by English Heritage while the surrounding land is owned by the National Trust.

• The circle was aligned with the midsummer sunrise, the midwinter sunset, and the most southerly rising and northerly setting of the moon.

• The builders of Stonehenge have featured it in a way that it encompasses sophisticated mathematical and geometrical understandings of the framework and the structural engineering of the construction.

• Stonehenge has a henge, or a ditch and bank, which surround the large stone circle.

• The stones of Stonehenge were placed in such a way that they increase in size towards the centre and alternate in shape between tall, thin pillar-like stones and stones of a tapering obelisk shape.

• Two types of stone were used for the construction of Stonehenge- the ‘bluestones’ which weighed almost four tons and were brought from 240 miles away. The other type of stone used was the ‘Sarsen’ stones which had a height of about eighteen feet and weighed twenty-five tons.

• It is anticipated that more than thirty million hours of labor was required for the construction of Stonehenge.

• Stonehenge is the most well known among the nine hundred stone rings which exists in the British Isles.

• Most archaeologists believed that Stonehenge’s use had been limited to the ritual activities of different Neolithic chiefdoms before 1950. However, its use as an astronomical observatory was an equally important function of the Stonehenge.

Howard Hughes in the cockpit of the Spruce Goose

Why built: In July 1942, the world was at war. America had just lost 800,000 tons of her supply ships to German U-boats. Henry Kaiser, famed industrialist and builder of “Liberty” ships, proposed a fleet of flying transports to safely move troops and material across the Atlantic. Kaiser approached Howard Hughes with his idea. Together they formed the Hughes Kaiser Corporation and obtained an $18,000,000 government contract to construct three flying boats.

Hughes and his team of skilled engineers designed a single hull flying boat capable of carrying 750 troops. The plans called for eight 3,000 horsepower engines, a mammoth fuel storage and supply system, and wings 20 feet longer than a football field. They called the prototype aircraft the HK-1, standing for the Hughes Kaiser design number one.

Delays and Constraints: Encountering and dealing with tremendous design and engineering problems, the Hughes team developed new concepts for large-scale hulls, flying control surfaces, and complex power boost systems. Hughes engineers created the first “artificial feel system” in the control yoke, which gave the pilot the feeling he was flying a smaller aircraft, but with a force multiplied two hundred times. For example, for each pound of pressure exerted on the control yoke by the pilot, the elevator received 1,500 pounds of pressure to move it.

The H-4 now resides at the Evergreen Aviation & Space Museum in McMinnville, OR

Adhering to the government mandate not to use materials critical to the war effort (such as steel and aluminum), the Hughes team constructed the Flying Boat out of wood. Hughes perfected a process called “Duramold” to create almost every part of the plane. Originally developed by Fairchild Aircraft Company, Howard Hughes purchased the rights to use Duramold in large aircraft. The Duramold process is a plywood-like series of thin wood laminations, with grains laid perpendicular to each other. Workers permeating the laminations with plastic glue, then they shaped and heated the pieces until cured. The result is a material that many engineers agree is both lighter and stronger than aluminum.

All of the research and development that went into the new seaplane delayed the construction process. In mid 1944, Henry Kaiser withdrew from the project, and Hughes took personal responsibility for all facets of the flying boat’s design and production. He renamed the gigantic seaplane H-4, representing his aircraft company’s fourth design.

After the war’s end in 1945, criticism of the project mounted. The Flying Boat prototype had exceeded the government’s funding allowance and the U.S. Senate formed an investigation committee to probe alleged misappropriation of funds. Hughes invested $7,000,000 of his own into the project to keep it going. While Hughes testified before the investigative committee in Washington, D.C., the Hughes team assembled the Flying Boat in the Long Beach dry dock. After his interrogation, Hughes was determined to demonstrate the capability of his Flying Boat. He returned to California and immediately ordered the seaplane readied for taxi tests.

Proof of Concept: On November 2, 1947, a crowd of expectant observers and newsmen gathered. With Hughes at the controls, the giant Flying Boat glided smoothly across a three-mile stretch of harbor. From 35 miles per hour, it cruised to 90 during the second taxi test when eager newsmen began filing their stories. During the third taxi test Hughes surprised everyone as he ordered the wing flaps lowered to 15 degrees and the seaplane lifted off the water. He flew her for a little over a mile at an altitude of 70 feet for approximately one minute. The short hop proved to skeptics that the gigantic craft could fly!
