Very few people can give an account of what it was like to spend Sept. 11, 2001, in the White House bunker.
Former Transportation Secretary Norman Mineta can.
When New York's Twin Towers were hit by planes and the White
House was evacuated that morning, Mineta rushed into the White
House underground bunker.
He says he worked with air traffic controllers, tracking American Airlines flight 77. Just then, he got a report from a police officer in Arlington County, Virginia, saying the officer saw an American Airlines flight go into the Pentagon.
And then, Mineta says, United Flight 93 vanished from radar.
America learned later that brave passengers helped bring down that plane over Shanksville, Pa.
Mineta says "maybe that plane was coming to either the Capitol or the White House. We'll never know."
The former transportation secretary grounded some 4,600 flights
over the U.S. that day.
