"A cellphone conversation between a passenger and his wife may indicate that an act of heroism may have kept one of the airplanes from doing damage and taking more innocent lives.

Tom Burnett, a passenger aboard United Flight 93, reportedly called his wife Deena and told her that the plane he was traveling on had been hijacked and that someone had been stabbed, according to the Knight Ridder news service. Burnett then told his wife ?We?re all gonna die, but three of us are going to do something.?

Burnett then reportedly told his wife ?I love you honey? before the call ended. United Flight 93 crashed just southeast of Pittsburgh. It was the only hijacked flight of four that didn?t crash into a building Tuesday.

A senior administration official said that the plane that crashed near Pittsburgh was viewed at the time as a potential threat to the White House and was a major reason for the evacuation of the presidential mansion shortly before the plane crashed.

It was not known whether the White House, or perhaps Camp David in the Maryland mountains near the Pennsylvania border, was indeed the target. "
