Update: Is it no coincidence  that The Franklin D Roosevelt Aircraft Carrier was the first and only Aircraft carrier or Ship in the fifties, equipped with Nuclear Weapons?. On 19 September at 11am a silver disc-shaped object followed a Gloster Meteor returning to RAF Topcliffe, and seen by observers on the ground. It rotated whilst hovering. It then travelled towards the west at high speed. On 21 September, six RAF planes followed a spherical object over the North Sea. It followed one of the planes back to the base.
