Some interesting tidbits:

The wide displacement of the plane's debris, one explanation for which might be an explosion of some sort aboard prior to the crash. Letters – Flight 93 was carrying 7,500 pounds of mail to California – and other papers from the plane were found eight miles (13km) away from the scene of the crash. A sector of one engine weighing one ton was found 2,000 yards away. This was the single heaviest piece recovered from the crash, and the biggest, apart from a piece of fuselage the size of a dining-room table. The rest of the plane, consistent with an impact calculated to have occurred at 500mph, disintegrated into pieces no bigger than two inches long. Other remains of the plane were found two miles away near a town called Indian Lake. All of these facts, widely disseminated, were confirmed by the coroner Wally Miller.

One telephone call from the doomed plane whose contents do not entirely tally with the hero legend and which is accordingly omitted in the Independence Day-type dramas favoured by the US media. The Associated Press news service reported on 11 September that eight minutes before the crash, a frantic male passenger called the 911 emergency number. He told the operator, named Glen Cramer, that he had locked himself inside one of the plane's toilets. Cramer told the AP, in a report that was widely broadcast on 11 September, that the passenger had spoken for one minute. "We're being hijacked, we're being hijacked!" the man screamed down his mobile phone. "We confirmed that with him several times," Cramer said, "and we asked him to repeat what he said. He was very distraught. He said he believed the plane was going down. He did hear some sort of an explosion and saw white smoke coming from the plane, but he didn't know where. And then we lost contact with him."
