Flying Saucers to Mind Control Declassified Military and CIA Secrets

A secret history

Government and military secrets can range from terrifying to amusing to downright absurd, but most are nothing short of intriguing. From a secret U.S. Air Force project to build a supersonic flying saucer to a now-famous World War II-era research program that produced the first atomic bombs to a plan to train domesticated cats to spy on the Soviet Union, here are 22 declassified military and CIA secrets.

Project 1794

In late 2012, the U.S. Air Force declassified a trove of documents, including records of a secret program to build a flying saucer-type aircraft designed to shoot down Soviet bombers. The ambitious program, called Project 1794, was initiated in the 1950s, and a team of engineers was tasked with building a disc-shape vehicle capable of traveling at supersonic speeds at high altitudes.

The declassified documents reveal plans for the plane to reach a top speed of Mach 4 (four times the speed of sound), and reach an altitude of 100,000 feet (30,480 meters). The project's estimated cost was more than $3 million, which in today's dollars would be more than $26 million.

Project 1794 was canceled in December 1961 after tests suggested the flying saucer design was aerodynamically unstable and would likely be uncontrollable at high speeds (let alone supersonic speeds).

Project Iceworm

In the 1960s, the U.S. Army embarked on a secret mission to build a series of mobile nuclear missile launch sites under the Greenland ice sheet. The objective was to house medium-range missiles close enough to strike targets within the Soviet Union.

The program was codenamed Project Iceworm, but to test its feasibility, the Army launched a cover research project called 'Camp Century' in 1960. Under this guise, engineers built a network of underground buildings and tunnels, including living quarters, a kitchen, a recreation hall, infirmary, laboratories, supply rooms, a communications center and a nuclear power plant.

The base, which was kept secret from the Danish government, operated for seven years. The program was canceled in 1966 after shifting ice created unstable conditions. Today, the crushed remains of Project Iceworm are buried beneath Arctic snow.

Project MK-ULTRA

During the Cold War, the CIA initiated Project MK-ULTRA, a secret and illegal human research program to investigate potential mind-control systems. The program's operators examined the effects of hypnosis, biological agents and drugs, such as LSD and barbiturates, on human subjects. Some historians suggest the program was designed to develop a mind-control system that could be used to 'program' the brains of potential assassins.

In 1973, then-CIA director Richard Helms ordered that all documents from Project MK-ULTRA be destroyed, but a formal investigation into the program was launched several years later. The project became the basis for several movies, such as 'The Manchurian Candidate' and 'The Men Who Stare at Goats.'

Area 51

Almost no other site has garnered as much attention from conspiracy theorists and UFO-enthusiasts as Area 51, a remote desert tract near Groom Lake in Nevada, roughly 83 miles (134 kilometers) northwest of Las Vegas. The intense secrecy surrounding the base sparked peoples' imaginations, and Area 51 was commonly linked to paranormal activities, including pervasive theories that suggested Area 51 hid aliens and UFOs.

In July 2013, declassified documents from the CIA acknowledged the existence of Area 51 for the first time, and confirmed that the top-secret site was used to test a variety of spy planes, including the well-known U-2 reconnaissance aircraft.

While Area 51, which operates as a detachment of Edwards Air Force Base in neighboring California, has never been declared a covert base, the research and activities conducted there were some of the nation's most closely guarded secrets.

Project Grudge

While Area 51 was not a top-secret base designed to study extraterrestrials, the U.S. Air Force did study the existence of UFOs. Project Grudge was a short-lived program launched in 1949 to study unidentified flying objects. The mission followed an earlier program, known as Project Sign, which published a report in early 1949 stating that while some UFOs seemed to be actual aircraft, there was not enough data to determine their origins. 

Critics of Project Grudge said the program solely set out to debunk UFO reports, and very little actual research was conducted. In his book on the topic, Edward J. Ruppelt, Air Force Captain and director of Project Grudge, wrote: '[I]t doesn't take a great deal of study of the old UFO files to see that standard intelligence procedures were not being followed by Project Grudge. Everything was being evaluated on the premise that UFOs couldn't exist. No matter what you see or hear, don't believe it.'

Operation Paperclip

In September 1946, President Harry Truman authorized a program called Operation Paperclip, which aimed to lure scientists from Nazi Germany to the United States following World War II. Officials at the Office of Strategic Services (the predecessor to the CIA) recruited German scientists to America to aid the country's postwar efforts, which would also ensure that valuable scientific knowledge would not end up in the hands of the Soviet Union or the divided East and West Germany.

Operation Paperclip's most famous recruit was rocket scientist Wernher von Braun, who would go on to mastermind NASA's Apollo moon missions.

Operation Northwoods

The tense relationship between the United States and Cuba during the Cold War led the Central Intelligence Agency (CIA) to hatch a slew of bizarre schemes aimed at taking down the Castro regime. While the goal of most of these covert operations (such as Operation Mongoose) was to assassinate Fidel Castro himself, other plans aimed to incite an all-out war between the U.S. and Cuba, experts have said. 

In 1998, the National Security Archive (NSA) — a non-governmental organization that publishes information made available through the Freedom of Information Act — posted declassified documents related to Operation Northwoods. The scheme, dreamed up in 1962 by the Joint Chiefs of Staff (uniformed members of the U.S. Department of Defense who advise the president and others), involved committing acts of violence against U.S. and Cuban civilians and then blaming those acts on the Cuban government, according to the NSA documents. These acts, which included faked terrorist attacks in U.S. cities, the hijacking of planes and the sinking of boats full of Cuban émigrés en route to the U.S., would then be used to justify a war with Cuba, according to the documents.

The Kennedy administration recognized the folly of Operation Northwoods and rejected it, according to news reports.
