My club DropZone is only up the road for there at Hinton, around 18 months ago we had a trainee doing their AFF level 1. He opened his canopy at 5k and proceeded to visually locate the DZ, what he locked onto and then headed toward was RAF Croughton about 5/6 miles away as the crow flies. By all accounts he lined up and executed a perfect landing on the main runway only to be met by wailing sirens and fully armed, weapons drawn MP's.
He was stripped of his rig, spread eagled on the tarmac and handcuffed at gunpoint, then duly led away and questioned by the Military Police. 3 hours later when they were satisfied that he wasn't a threat to security was he allowed to contact the DZ, the CCI who was one step ahead of the off target lander dispatched a vehicle with the jumpers instructor on board to the base to help smooth things over. Needless to say he got back safely and still holds the club record for the longest off target landing and is still known affectionally as " Captain America " within the parachuting fraternity.......
