The Pentagon Attack: What the Physical Evidence Shows

The Pentagon attack left debris scattered over a wide area. Judging from the dimensions of punctures in the facade the vast majority of debris ended up inside of the building. Nonetheless, the few photographs that show portions of the lawn near the building show an extensive debris field, easily accounting for the portions of a 757 that did not penetrate the building.
