F-16 Pilot Heather Penney Tasked to Take Down United Flight 93 on September 11

And the F-16 she piloted was not armed for combat, so she essentially was on a Kamikaze mission to take down the hijacked airliner if necessary.

See Washington Post, "F-16 pilot was ready to give her life on Sept. 11."

Also at Daily Mail, "I'd be a kamikaze pilot: Fighter pilot recalls her would-be 'suicide' mission to take down United 93 - and the heroes who did it for her."
