I've read every post in this thread that I can. As far as I can tell, nobody has asked this so far:-
Wouldn't safety be enhanced if every flight started as far away from the far end of the runway as possible? - i.e no starting from intersections with 300m of empty runway behind you.
It might not have made a difference in this accident, and I'm not sure whether or not they did start at the end or part way along the runway. Anyone else got that info?
