Conspiracy theorists have circulated increased rumors in recent months that the meeting between President Eisenhower and people from another planet took place.
But the claims from Tymothy Good, a former U.S. Congress and Pentagon consultant, are the first to be made publicly by a prominent academic.
Speaking on Frank Skinner’s BBC2 current affairs show Opinionated, Timothy Good said that governments around the world have been in regular contact with aliens for many decades.
“Aliens have made both formal and informal contact with thousands of people throughout the world from all walks of life,” Timothy Good added.
Asked why the aliens don’t go to somebody “important” like President Barack Obama, Timothy Good said: “Well, certainly I can tell you that in 1954, President Eisenhower had three encounters, set up meetings with aliens, which took place at certain Air Force bases including Holloman Air Force base in New Mexico.”
The former consultant added that there were “many witnesses”.
Dwight D. Eisenhower, who was president from 1953 to 1961, is known to have had a strong belief in life on other planets.
The former five-star general in the United States Army who commanded the Allied Forces in Europe during the Second World War, was also keen on pushing the U.S. space programme.
His meeting with the cosmic life forms is said to have taken place while officials were told that he was on vacation in Palm Springs, California, in February 1954.
The initial meeting is supposed to have taken place with aliens who were “Nordic” in appearance, but the agreement was eventually “signed” with a race called “Alien Greys”.
Timothy Good added: “We know that up to 90 per cent of all UFO reports can be explained in conventional terms. However, I would say millions of people worldwide have actually seen the real thing.”
According to classified documents released by the Ministry of Defence in 2010, Winston Churchill may have ordered a UFO sighting to be kept secret.
The UFO was seen over the East Coast of England by an RAF reconnaissance plane returning from a mission in France or Germany towards the end of the war.
Winston Churchill is said to have discussed how to deal with UFO sightings with President Eisenhower.
