EXPLOSIVE JFK files have revealed that Lee Harvey Oswald and his killer Jack Ruby met in the weeks before Kennedy was assassinated.

The pair were seen together at Florida's Key West airport in 1963 and were overheard speaking in code about "Big Bird", according to the documents.

They were part of a group of 30 or 40 "hippie looking" people who were on their way to Cuba to cut sugar cane, airport manager George Faraldo told investigators.

This bombshell will shed new light on the truth behind JFK's assassination and whether Oswald was to blame for the former president's murder.

Ruby, whose real name is Jacob Rubenstein, shot dead Oswald, 24, two days after the presidential assassination in November 1963.

But just weeks before, Oswald and nightclub owner Ruby were apparently both part of a large group of "mostly young" people heading to Cuba.

Mr Faraldo told the FBI that Ruby and Oswald were dressed casually in a sport shirts and trousers.
