How Realistic (or not) was the crash scene in Flight? In the movie Flight, Denzel Washington's plane loses one engine and some other controls. To keep the plane gliding, he inverts the plane until it reaches a very low altitude. At the last second he flips it back right side up so that the belly of the aircraft takes the grunt of the crash landing.

Obviously this is all hollywood and takes a lot of creative license, but I'm a bit curious as to how realistic it was. Would you actually be able to fly a large jet upside down like that?
It's apparently loosely based on Alaska Airlines Flight 261 and like in the actual incident, I don't think he deliberately inverts the plane. In the actual event, the horizontal stabilizer gets jammed in an extreme position thus forcing the plane to invert. Now if it were possible to fly a commercial airplane that big inverted, Alaska Airlines too would've landed safely eventually (which didn't happen, despite the pilots trying to fly it upside down according to the CVR transcripts).
