Having been part of an Air Force detail securing A/C crash sites, I can attest that each one is different. There is a "smell" associated with most crash sites, but the pattern of debris and the burn area differ with the terrain, cause of crash, type of aircraft, and many other variables. It is not unusual for some items to escape burn damage.
Can't believe it. I stopped reading all about it once I heard that indeed the plane was found without any survivors.
If that was the case, that is certainly odd.
A plane crash is not pretty...they may not have been attached to her, or all of her, after the incident.
