ATH911......there are NO RESOURCES available online to even begin to attempt to address that question.
Unlike the situation in NYC (airplanes mostly INSIDE each Twin Tower, although SOME debris ejected, due to momentum) where the final airplane debris
was MINGLED up in the collapse of the much, much larger building debris, AFTER the fall. AND, of course, intense fires raged (as they did at the
Pentagon).
THREE airplanes, impacted INTO buildings. With fires. Aluminum (the primary metal in airframe construction) WILL MELT quite easily. I know this
first-hand, as one of the Cessna 150s (FAA registration number
N8282F...if you wish to look it up...I had a LOT of hours in that airplane) that
my family owned crashed, and burned, due to a rental pilot's poor handling as he practiced landings. (He escaped.....the fire started AFTER he
exited the airplane). MOST of that Cessna airplane was a molten puddle of aluminum....except, of course, for those parts that were made of different
metals.
American 77 was MOSTLY inside the Pentagon.....fragmentation at impact shed some parts in many directions, it is the nature of the forces
involved....the PHYSICS involved.
As of yet, I have no links nor info on any final assessment of total recovered American 77 airframe debris. THAT, however, would be an interesting
road to explore......
