from all the years researching 911 this is the first time I heard of a bridge. and funny thing is.. if the underground structure to the WTC had been in fact compromised the whole of Manhattan would have been flooded. the retaining wall ( others call it the bathtub) survived under the WTCS ..tell him to show us the bridge.. talking out his arse no doubt.. and if in fact he was there he would have heard/felt/seen explosions, so who is this guy!
