Russian Plane Crash

[abaris]

If the plane was largely intact and its engines functioning normally When for whatever reason it suddenly climb from cruising speed and altitude to the point of stalling, then the plane would likely Experience large gain in altitude before the actual stall.

That's hardly possible with airbus systems in good working order. A 320 pilot once demonstrated to me what he could and couldn't do without the systems stepping on the brakes. A climb to a stall is virtually impossible, even if all the systems are disabled. Unless something took care of the safeties before that.
