The word from Martin is that he and Tony were in one mile battle spread at 20,000 feet under the control of HMS Invincible. Ardiles was inbound on a reciprocal 10,000 feet above. Martin had the only serviceable radar but never gained radar contact. At about ten miles Martin saw the missile release and guide towards him. He describes a very strong white smoke trail just like the missiles he has shot and seen shot. At no stage did he get any indications on his RWR. He carried out the evasion manoeuvre and was on his way back up when he saw Tony's shot against Ardiles above him.
What is curious is that the controller reported a second target exiting the area at high speed after Ardiles was splashed. As far as I know Ardiles' wingman went u/s on start and never accompanied him to the Falklands.
I am trying to contact Donadille (later shot down by Steve Thomas) to see if he can shed any light on the situation as he was apparently airborne in the area at the time.
