Those engines look pretty smart and add a nice touch to the wreckage. I've just been thinking about this, and far be it for me to give advice, but would the windows of such a wreck still be intact given the force of the impact and debris, or would they be cracked and broken open? possibly with metal bars etc poking through them/bits of tree (especially if it's skidded in at a low angle) etc? Not sure how easy that would be to do though.
