That is exactly right. I don't think they were able to recover any switch positions. However, they were able to look at some of the valves and determine their positions at impact.
User997 said:I have a hard time imagining that there was enough of the aircraft left to even be able to know where the switches were set. I figured a nose dive from the kind of altitude, and the ensuing monsterous hole it drilled into the ground, the aircraft wouldn't be much more then a crushed tin can. (??)
