Having been to several rotary wing crashes, you are going to be looking at spinal and leg injuries. If it isn't going to burn or sink DON"T MOVE ANYONE.

If you are knowledgeable about the aircraft, or it is really well marked, you might kill the battery breakers (or whatever the right term is). No juice, fewer sparks.

If it is military, and burning, you may have ammo cooking off once it gets too hot. If it is a gunship, you might consider finding another zip code to be in....
