Today marks 55 years since JFK was fatally shot on a presidential motorcade through Dealey Plaza, Dallas, US.
But controversies have surrounded his death ever since, with claims ranging from assassin Lee Harvey Oswald “did not act alone”, to a Mafia gangster ordering the hit.
There is another conspiracy, though.
It claims the late president had uncovered proof his top officials had been in contact with extraterrestrials – and was about to reveal it to the world before he was shot.
Experts claim to have discovered a letter from the Majestic 12 – a secret government committee formed in 1947 which were responsible for investigating the possibility of alien life on earth.
If the Majestic 12 document is authentic, they suggest the government were aware of and in contact with extra-terrestrial beings.
The letter – which was reportedly recovered from a fireplace – was from the director of the CIA, Alan Dulles, under Kennedy’s presidency.
Dulles’ alleged letter claims “Lancer” (which was a code name for the president at the time) made inquiries regarding the CIA’s activities in regards to aliens – an act which the organisation could not allow.
Robert M. Wood – a retired aerospace manager – told the History Channel’s Ancient Aliens series: “The inference of the scorched memo is that if JFK keeps doing what he’s doing, he may be is a problem.”
In the letter, Dulles identifies a number of actions which that could be taken, one of which implies that if Washington does spot asking questions ‘it should be wet’.”
“It should be wet”, Wood recalls, was a phrase used by Soviet spies as a code word for assassination.
Lawyer Douglas Caddy also claims JFK was assassinated in order to protect the CIA’s top secret information in relation to alien life.
Caddy was apparently “close friends” with E. Howard Hunt – an officer in the CIA during Kennedy’s presidency who was caught up in Nixon’s infamous Watergate scandal several years later.
Looking back at his last encounter with Hunt in 1975, Douglas Caddy said: “Out of my own curiosity I said to him: ‘Howard, why was John Kennedy assassinated?’”
To which Hunt reportedly replied: “John Kennedy was assassinated because he was about to give our most vital secret to the Soviet Union.”
When asked what this secret was, Hunt replied: “The alien presence.”
Theories of an alien cover-up are still a big issue today, with unexplained footage from the SpaceX live feed leading many to think the existence of aliens is being hidden from us.
Others claim JFK was murdered by the mafia after double-crossing a boss known as “The Godfather”.
