Several people have said that the A/P did the best possible job under the circumstances. I'm sure the crew did what any good crew would have done in that situation, but.....
If they had disconnected the A/P when the engines failed to respond to the manual throttle movement and flown the aircraft towards the grass, I bet they would have had enough energy for a decent flare. The landing gear might not have liked coming down in the bog, but I'd take that over a no-flare, near the stall plonk-down. Might have saved some poor sod a broken leg.
Of course you don't expect your jet to turn into a glider on short final and it is easy to speculate with the benefit of hindsight. I'm sure somebody will try it in the simulator, let us know how you get on.
Flame on.
