This analysis indicates that all three of these engines are too small
to match the engine component photographed at the Pentagon. Some
sites also suggest the part might be from the aircraft's auxiliary
power unit (APU). An APU is essentially a small jet engine mounted in
the tail of an aircraft that provides additional power, particularly
during an emergency. However, APUs tend to be much smaller than jet
engines, and the component pictured at the Pentagon is too large to
match any found in an APU. It has also been suggested that the attack
was conducted by a cruise missile like the Tomahawk or Storm Shadow,
but these and other weapons are powered by engines no more than 15
inches (38 cm) across. These powerplants are obviously far too small
to account for the Pentagon wreckage.
