Salute!
Dunno if the USAF Talon birds have suppression, but think so. I doubt the USMC birds have such, but you never know. Shame, but my neighbor two doors down just retired from flying the USAF MC-130, but I am 1200 milles away now and can't get with him easily.
BEagle is right about forensic evidence, although seems witnesses reported many secondaries after the plane hit the field. That will complicate things unless a piece of debris from a half mile away has "traces".
Gums opines...
