In one of the many reports on the 2001 terrorist attacks on the United States, the Washington Post recounts the story of two F-16 pilots from the 121st Fighter Squadron of the Washington, DC, Air National Guard, who were some of the first to respond to the attack.  As also reported at MSNBC.com,

the F-16 jets they were rushing to get airborne were largely unarmed, recalls one of the pilots, then-Lt. Heather Penney, leaving them one option to take out the wayward plane [Flight 93]: a kamikaze mission.

Loaded with a few rounds of training ammunition in their guns, the flight lead primarily planned to use the aircraft themselves as weapons.

“As we were putting on our flight gear [Col Marc Sasseville] looked at me and said, ‘I’ll ram the cockpit.’ And I had made the decision that I would take the tail off the aircraft,” Penney recalled.

The Post notes Penney’s pre-takeoff prayer:

She muttered a fighter pilot’s prayer — “God, don’t let me [expletive] up” — and followed Sasseville into the sky.

Alan Shepard might take issue.
