Well, one vote against.

I think the less info the better. While the dead observer was one of the few things the original game said to reveal

"Except for smoke, fire, observer killed, and results which cause the destruction of the plane, all damage results are secret and should not be revealed to other players."

...
My opinion is that this is way too much information and makes getting those damages-- already a huge pain-- into something a lot worse. If my opposition all knows I can't do a restricted move or go fast--as soon as the damage happens-- I think I'd be a lot more prone to head for the exit side of the board. A damaged plane would certainly be a lot easier to finish off, and I don't think that would be good for the game overall.
