The shortage of available facts [about the crash of Flight 93 on September 11, 2001] did not prevent the creation of an instant legend ... that the US government and the US media were pleased to propagate, and that the American public have been eager, for the most part, to accept as fact. The absence of official information has led to lively and often well-informed debate [on] the internet (see www.flight93crash.com.) There are ... a number of important unanswered questions ... based on evidence, as well as on a manifest absence of candour on the part of the authorities - which the national US media, typically so sceptical and inquisitive, have shown a curious reluctance to ask. The alternative theories, both of which have been denied by the US military and the FBI, are a) that Flight 93 was brought down by a US government plane; and b) that a bomb went off aboard. If doubts remain despite the denials, if conspiracy theories flourish, it is in large part because of the authorities' failure to address head-on questions, [including:] 1. 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 ... 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 [more than a mile] away . Other remains of the plane were found two miles away near a town called Indian Lake. 2. A federal flight controller [was quoted] a few days later in a newspaper [stating] that an F-16 had been "in hot pursuit" of the hijacked United jet and "must have seen the whole thing". Everything is speculation - that is the problem with the story of Flight 93.
