East England's 'secret' role in Cuban Missile Crisis
In October 1962 RAF Waddington in Lincolnshire was home to the Vulcan bombers of the RAF's V Force.
But the role that it and RAF Harrington played in the Cuban Missile Crisis, where Soviet nuclear warheads were placed in Cuba, was kept secret at the time.
A group of aviation historians are collecting first-hand accounts of the Cuba crisis but they have made a remarkable discovery.
Some of the accounts do not match the versions on official files.
