My 9/11 theory about United flight 93, the one that crashed into the ground:

It blew up in the air, before it hit the ground. Pieces of the plane were scattered around for MILES. The hijackers said they had a BOMB, and the passengers said they were going to try and over power the highjackers. Maybe the hijackers werent bullshitting around, maybe they were serious, and detonated the bomb when they realized they were not able to control the passengers in the plane.

"Finding the flight data recorder had been the focus of investigators as they widened their search area today following the discoveries of more debris, including what appeared to be human remains, miles from the point of impact at a reclaimed coal mine.

Residents and workers at businesses outside Shanksville, Somerset County, reported discovering clothing, books, papers and what appeared to be human remains. Some residents said they collected bags-full of items to be turned over to investigators. Others reported what appeared to be crash debris floating in Indian Lake, nearly six miles from the immediate crash scene.

Workers at Indian Lake Marina said that they saw a cloud of confetti-like debris descend on the lake and nearby farms minutes after hearing the explosion that signaled the crash at 10:06 a.m. Tuesday."

"In a morning briefing, state Police Major Lyle Szupinka confirmed that debris from the plane had turned up in relatively far-flung sites, including the residential area of Indian Lake. Investigators appealed to any residents who had come across such debris, in the surrounding countryside or even in their yards, to contact them, emphasizing that even the smallest remnants could prove to be important clues.

"This is not a finite [crime] scene," said Crowley. "As things are discovered, it expands and contracts.""

"Eight miles away in New Baltimore, Melanie Hankinson said she found singed papers and other light debris from the crash, including pages from Hemispheres Magazine, United's in-flight magazine. Crowley said the material could easily have been carried on the wind."

"Before the plane crashed, killing all 45 on board, several passengers called loved ones, telling them that their plane had been hijacked, and that their captors said they had a bomb. At least two passengers said they would fight back, apparently after learning that the hijackers intended to use the plane as a jet-powered missile like those which smashed into the World Trade Center Towers and the Pentagon."

Ye, there were witnesses who actualy saw the thing crash, appearently it flew upside down for a while before it actualy hit the ground.

The complete plane hit the ground at 575 mph and left a crater 50 feet deep in the shape of the airplane.

Where do you get your information?
