Chaps

I know nothing about this accident but I would suggest that the ‘famous’ YouTube video of a late unstuck quoted on post 18 this thread is not what it seems.

Aeroplanes need two things to unstick – speed and angle of attack. At unstuck the aircraft on YouTube certainly had speed but it had a negligible nose up attitude showing a low angle of attack. In short this is what you see when a wind up merchant leaves his aircraft on the ground until just before the end of the runway and then (thanks to the excess speed) is able to unstuck and fly away without the normal post rotation high nose up attitude.

Works every time with a lot of onlookers - especially with a large aircraft that always seem to be crawling along after takeoff when compared to its smaller brethren.
