Formerly confidential files obtained by alien researchers detail the account given by senior senator Richard B Russell and two aides of seeing the "flying saucers" TAKE OFF.
At the time, Sen. Russell was on a Soviet-era train during a fact-finding mission to Russia, nearly 60 years ago.
Sen. Russell, was a former chairman of the Armed Services Committee and one of America's most influential senators until he died in 1971 after serving for 38 years.
Documents obtained by the Fund for UFO Research (FUFOR) said Sen. Russell was travelling with his two aides in the Transcaucasus region on October 4, 1955 at about 7 pm, when the incident occurred.
He is said to have looked out of the window and spotted two disc-shaped UFOs 'taking off' from a spot near the railway tracks.
According to reports, the documents state how Sen. Russell hurriedly called over aide Lt Col Hathaway and interpreter Ruben Efron to the window, with them both seeing the two crafts 'take off'.
He and the aides reported the sighting to US Air Force and security agencies once at the US embassy in Prague, in then Czechoslovakia, but the account was kept strictly confidential.
Lt Col Thomas Ryan, air attaché at the embassy, filed a top secret Air Force intelligence report on the trio's sighting on October 14, 1955 after meeting them.
The document said Lt Col Hathaway told Lt Col Ryan: “I doubt if you are going to believe this, but we all saw it. Senator Russell was the first to see this flying disc we’ve been told for years that there isn’t such a thing, but all of us saw it.
“One disc ascended almost vertically, at a relatively slow speed, with its outer surface revolving slowly to the right, to an altitude of about 6,000 feet, where its speed then increased sharply as it headed north. The second flying disc was seen performing the same actions about one minute later. The take-off area was about 1 to -2 miles south of the rail line.”
The men, and a fourth unidentified witness, were also interviewed by CIA agents.
The documents state Mr Efron reported visibility as "excellent" and the UFOs appeared to “glide” as “no noise was heard and no exhaust glow or trail was seen.”
fourth unnamed person said one UFO had a “slight dome” and a “white light” on top.
All said the disc had a pinkish-white glow and rose “vertically with the glow moving slowly around the perimeter in a clockwise direction, giving the appearance of a pinwheel.”
John Foster Dulles, US Secretary of State, was briefed on October 18, 1955 and on November 4 the FBI penned a memo stating that Lt Col Hathaway’s testimony “would support existence of a flying saucer.”
It is understood the men never spoke publicly about what they saw, but details were leaked to a reporter for the Los Angeles Examiner who approached Sen. Russell.
His response to journalist Tom Towers was: “I have discussed this matter with the affected agencies of the government, and they are of the opinion that it is not wise to publicize this matter at this time. I regret very much that I am unable to be of assistance to you.”
The CIA, FBI, and Air Force documents remained confidential for 30 years before being declassified in 1985.
However, it was not until FUFOR obtained them under a Freedom of Information Act request that their details emerged.
Dr Bruce Maccabee, FUFOR chairman, told http://www.inquisitr.com: “These long secret documents are of major importance because they show for the first time that one of the most powerful US Senators witnessed and reported a UFO.”
He believes that the men would have "no doubt advised not to talk.”
The researcher added: "These documents provide startling new evidence that UFOs exist” and the case was "unique because the CIA took it seriously".
In January, the Paradigm Research Group petitioned the White House to consider holding open congressional hearings so the public "hear the truth about evidence of UFO and alien visitations."
