Re: United 93
bhai jaan that was probably a Delta flight.. there was one flight which was force landed and deplaned the same day due to some bomb threat or other security concerns... but nice try by some people to spread more rumors.
Flight 93 did crash however the causes are still unknown. The widely scattered debris indicates disintegration mid air, which could be due to an explosive, or a missile fired by some fighter to bring it down. There is nothing conclusive either in support or against these theories.
A lot can be gained from the black box but it took so long to come out that the contents are no longer trustworthy. Also the filmmakers (just like the 9/11 commission) relied totally on the cell phone calls to create the script. However a majority of telecom providers have confirmed that the chances of getting a cellular connection at those altitudes and the duration and clarity of not one but several calls was impossible. The Airphones however worked but those calls are sealed and were not considered by the producers or the 9/11 commission.
