Odd thing that time dilation stuff. I saw a Phantom crash at Coningsby back in '75 (XV 416 for the pedants) . I was out on an aircraft and looked up to see a 'toom doing a roller but trailing black smoke. The Speys didn't smoke unlike the J79 so that was unusual in itself. I kept my eye on it and the crew banged out, the a/c rolled slightly and crashed into the River Witham. I would say the whole episode lasted a couple of minutes until I was told by a mate in ATC that the whole incident had lasted about 10 seconds.
Also have you noticed that from the time you chop the throttle, do the flare and actually have tires on tarmac can seem quite a while but when you watch someone else do it from the ground it takes no time at all. Or maybe I just float down the runway for miles........
The eyewitness account was thoroughly chilling, glad the man only had minor injuries.
