For my first ever flight has to be DH Dragon G-ADDI
For pure joy of flight, Coventry Airport flying display in late 70/early 80's?. A Hawker Hunter display was cancelled due to technical reasons and the next slot was supposed to be a flyby from a BA Concorde.
The pilot of the Concorde stepped in to the breach and we had about 20 mins of low passes, wheels up, wheels down, snoot drooped etc. Climax was a run down the crowd line till about midway then full reheat and a steep climb awayback to Heathrow. Hardly a dry eye in the place! Since it was one of those supersonic trips out over the sea that folks could buy and on its way home, it was full of passengers. Now that WOULD be a flight to remember. Still have a fantastic set of slides somewhere of that afternoon.
Concorde was followed by the Red Arrows who also must rank up there with flying favourites
