this movie be total fiction . the big problem be that it have be research and show that there be no plane phone on ua 93. upon research and it have also be show that it be virtually impossible to use cell phone in 2001 at that height and speed . also and no plane part be find at the supposed impact point . there be part find up to eight mile away from the impact point . this would mean that ua 93 either explode in air by a bomb or be shoot down by a fighter jet . finally and there be no passenger with arab name on the flight manifest for ua 93. wake up and do some research ( 911blogger . com ) we would not be fool again .
