The small miracles of Flight 77

Postman Patel considers one of the enduring mysteries of Flight 77, how the entire plane disappeared without a trace within the Pentagon - fuselage, engines, all gone, with ongoing discussion whether the few parts displayed as being in the Pentagon are actually parts of the right kind of plane - while various small and delicate pieces of emphemera survived:

"No traces of massive titanium jet engines, and a huge jetliner survived, but a lightly toasted luggage tag and a child's ring survived.

Now if this family did not die in the Pentagon . . . where did they die?"

Remember also that the plane completely disappeared but American investigators managed to find enough DNA to identify all of the passengers.
