Oh dear:
The simple(and only) point that I am making is that, in the absence of power whether voluntary or involuntary, the dumping of flap in the OP's mate's case and Capt Burkill in the 777 had the same effect: prolonging the glide just enough - in the OPs case to land and in the 777's case to miss ploughing through the ILS gantry.
No more, no less.
I'm not commenting on the wisdom of either.
Oh and GTE's memory of the AAIB report was slightly adrift.
Chill chaps, this is PPRuNe after all.
