But a controversial new book The Presidents And UFOs: A Secret History From FDR To Obama claims that a number of US leaders have known of evidence proving that
aliens have visited Earth leaving spaceship debris, the occasional alien corpse and thousands of UFO sightings.”
Headquarters has come to the determination that the mystery airplanes are in fact not earthly and according to secret intelligence sources that are in all probability of interplanetary origin,” wrote US Army chief of staff general George C Marshall to president Franklin D Roosevelt in March 1942, according to a recently leaked memo.President Roosevelt replied urging the “finding of practical uses for the atomic secrets learned from the study of celestial devices”.And in another memo Roosevelt wrote of “coming to grips with the reality that our planet is not the only one harbouring intelligent life in the universe”.
“UFOs exist and extraterrestrial life has visited Earth,” says Holcombe, 71.
“The accumulation of evidence is so great that no reasonable person can any longer deny their existence.”
Millions have long suspected that not all UFOs could be explained away as experimental aircraft and weather balloons.
The US’s Area 51 Air Force base in Nevada is rumoured to hide alien corpses and their spaceships as depicted in movie Independence Day.
Many believe there is a secret President’s book handed to each new incumbent of the Oval Office revealing the existence of aliens, just like the one in the film National Treasure 2.
The US even seems to be moving towards publicly acknowledging the existence of alien life.
It changed colour to blue, then red, then white before racing away.
“It didn’t have any solid substance to it,” said a mystified Carter, who filed a UFO report.
But all presidents were given ample evidence of the existence of extraterrestrial life and told to keep it secret rather than scare an anxious public, claims the book.
President Harry S Truman drew a veil of secrecy over the 1947 alien spaceship crash near Roswell, New Mexico, and the alleged crash of a second alien craft almost simultaneously about 140 miles away on the San Agustin Plains.
Truman had supposedly created the “Majestic 12” in 1942: a secret committee of scientists and military to cover up extraterrestrial activities.
Late in the Second World War Dwight D Eisenhower met with Winston Churchill to discuss an RAF reconnaissance aircraft’s close encounter with a UFO near the English coastline.
I don’t think Britain or the US is going to admit that alien life has been visiting Earth for some time
“Kennedy wanted to share alien technology with the Soviets and there were powerful people who refused to let that happen.”
President Richard Nixon authorised a UFO documentary using secret footage of an alien craft landing during his re-election campaign in 1972 but the project was axed by intelligence chiefs, claims Holcombe.
“Nixon believed that a limited level of UFO disclosure would ensure his place in history,” he adds.
While running for office Gerald Ford, Carter and Clinton all demanded government openness about UFOs but fell silent once elected to the White House and privy to alien secrets.
Holcombe says he found evidence suggesting that several alien bodies have been studied by the US military and alien technologies copied.
Yet despite recent calls for greater openness about UFO encounters he says: “I don’t think Britain or the US is going to admit that alien life has been visiting Earth for some time.
“But they may be forced to admit it if extraterrestrials make their presence known.
“Many laws have been broken to keep this secret.
“It’s been the greatest cover-up in the history of mankind.
“But all it takes is one alien spaceship over London or Washington DC and the world will never be the same again.”
