I remember seeing a C152 with long range tanks fitted and huge photographer plus loads of cameras and not so huge but pretty big pilot fill her up and takeoff from inverness. Definately shut both the doors at the same time or its the door popping open game.
Normally you would expect a light to be off the deck before the intersection nope they were right down to the numbers when they inched off the ground and just cleared the hedge and had to turn towards the water to miss the woodchip plant.
We reckoned they must have been over a 100kg above MTOW.
