Langley Air Force Base was the second military base that launched fighter jets to defend America in response to the terrorist attacks on September 11, 2001. Three of its F-16s were ordered to take off toward Washington at 9:24 a.m. that morning, but by the time they were airborne, more than 40 minutes had passed since the first attack on the World Trade Center, and almost half an hour since the second.

Furthermore, the pilots were hindered by an extraordinary combination of confusion, communications problems, conflicting orders, breaches of protocol, and other difficulties. Consequently, when the Pentagon was hit at 9:37 a.m., the jets were further away from it than they'd been when they took off. According to witnesses on the ground, fighters did not arrive over the Pentagon until around 10:40 a.m.--more than an hour too late to protect it from the attack.

A close examination of publicly available accounts raises the possibility that deliberate attempts were made to sabotage the ability of the Langley jets to respond to the 9/11 attacks, thereby paralyzing normal, well-practiced procedures. In this article, I focus on three particular aspects of the jets' response.
