No conspiracy theories here, just speculation: If TWA800 had been infected with suicidal terrorists - especially suicidal terrorists with a bomb - shooting it down would have been a military judgement call. Covering it up after the fact would be a national security judgement call. Although there's no is clear evidence that Flight 93 over PA went down as a result of heroic action be passengers, we now know that the order had been given to fire upon it if it did not retreat from its vector toward Washington.
That is an amazing statement. The same kind of national security that failed to detect critical weaknesses in airline security?
If TWA800 was a terrorist incident, the reason for the cover-up was probably to prevent the same kind of economic tremors that the more recent bombings have caused. By avoiding confronting the truth, however, the damage has only been magnified.
Lies have this funny way of boomeranging. Too bad more of our brilliant bureacrats and politicians don't understand that.
