Only two actual aircraft objects are on display. The aircraft fuselage fragment and marked fuselage section are exhibited next to some steel columns from the WTC. The fuselage fragment shows the passenger window frame quite clearly, while the marked fuselage section appears to be part of the wing box as it is painted light grey and has stringers that are not of the type used in the fuselage.
Also on display is the Department of Justice telephone that Ted Olson received a phone call from his wife Barbara, calling from American flight 77.
This plane is built to withstand anything... except a bad pilot.
