not sure which 9/11 doc has it, but there's great (as in hysterically implausible) footage of either a NOVA or PopMech "expert" explaining how all the debris became essentially a fluid that continued through/into the building.
Disintegrated on impact. Although I think they found the fan blade turbine of a different engine further inside the complex. Something about the impact caused it to become smaller and a different model/design.
