I absolutely agree that is possible the pilots aren't the cause for the crash at all. What I'm saying is that from what the blackbox reveiled so far they didn't act according to what normal procedures would be and what you'd expect.
I'm just extremely interested in an actual reason for a nose up in that situation. You and for example IvanK defended the pilots behavior but on what basis? Procedures during a stall warning are as seen above: Nose down!

This is exactly why Bongo is suggesting people who aren't pilots(ie, desktop pilots), have absolutely zero place commenting on issues like this..
Cant think of one situation why you would pull up during a stall.. skip to 1:20
This video deals primarily with turbo props, and icing(which was likely what happened in Buffalo). Now, do i think this is what the pilots in this case were doing/thinking.. No.. but I think you could see, knowing what you are talking about, and not knowing what you are talking about(cant think of a single reason to pull up during a stall), are very different things..
Those pilots had a tremendous amount of information being thrown at them. And most of it, was miss-information, that simply didn't make any sense. A blocked pitot tube is a horrible thing, compound that with IFR conditions, and you've got a real mess on your hands..
From the wiki page on the incident
"Roughly 20 seconds later, the pilot decreased the plane's pitch slightly, air speed indications became valid and the stall warning sounded again and sounded intermittently for the remaining duration of the flight, but stopped when the pilot increased the plane's nose-up pitch."
Here is a situation where, pitching up stops the stall warning, and dropping the nose restarts the stall warning, no valid airspeed data, and no visual reference to tell what is right, and what is wrong. You think there is a textbook solution to this? Hindsight is 20/20, and armchair pilots have the luxury of it.. These guys didn't..
If you aren't a pilot, you should probably keep quiet, because there is a damn good chance you don't have a clue what you are talking about(especially what these guys went through). After all, you cant think of a single situation where you would pull up in a stall..
