The number of shills making the same argument "A plane is a missile" and "I have people who actually witnessed the plane hitting the pentagon" and other reddit-style shilling makes you wonder if this was the real target ...
They wanted to hit a precise spot at the Pentagon, and leave the building standing. In NYC, they had planted devices in the 3 buildings to bring them down, so a precise hit was not as important. That's why they needed to use a missile combined with pre-planted explosives at the Pentagon.
