Wiki: "Flight 77, flying at 530 mph...crashed into the western side of
the Pentagon...The front part of the
fuselage disintegrated on impact, while the mid and tail sections moved for another fraction of a second, with tail section debris penetrating furthest into the building.
[40] In all, the airplane took eight-tenths of a second to fully penetrate 310 feet (94 m) into the three outermost of the building's five rings
[42] and unleashed a fireball that rose 200 feet (61 m) above the building"
