This did not happen to me but a friend who I worked with at the time on the apron at EGCC Manchester.
He had a holiday planned in a few weeks time and he knew which aircraft he would be flying on, a Laker DC10, so he brought his cine camera to work and filmed it taxiing out and taking off. Then on the day of his flight he filmed the rest of the trip in stages etc, then on his return he edited the movie and put the bit he filmed where the aircraft was taking off after the bit where his wife and children were boarding , the movie looked good. Then one day he was showing it to a member of the family and they asked how he managed to film the aircraft taking off if he was on board. His reply was rather quick witted, he said, "Well I'm well respected at the airport and I asked the skipper if he wouldn't mind me filming the takeoff and come back for me."
