FlightDetent. All we know is that during an approach somehow the aircraft ended up on the other end of the runway with a hight rate of descent and a high energy impact. We do not know what altitude or speed it was going at. The only data we have seen is ameature data and not from an official source. So to say it climbed and increased in speed is not necessarily true. And notwithstanding that fact, you can stall the aircraft at ANY airspeed. It's angle of attack that will spoil your day and not necessarily airspeed or 'speed' to which you refer.
ManaAdaSystems - like I said before, if windshear is reported then it could very well the reason why the did it. If there was a sign of windshear then I'd want to get the hell out as quickly as possible, not at a leisurely 1,000-2,000 FPM. That simply is not enough for an escape manoeuvre for my liking. And which one it is? It is 1000FPM or 2000FPM. They're both very different figures!
