they are disabling the escape routes from Manhattan...

That is a scary thought and is worth thinking about. However, like a poster said, sometimes shi'ite just happens.

Course it wouldn't take much to close down the tunnels into New Jersey. Are flammable materials allowed to go through there? Not like terrorists really bother to play by the rules.

Can't speak to NJ, but I've been in the control room for the Mercer Island (WA) tunnel. Their systems are set to dump a LOT of foam to fight any such fire, so such an attempt in that tunnel, or the nearby Mount Baker tunnel in Seattle, wouldn't go far.

And no, "flammable materials" aren't allowed there (like that rule would stop a jihadi).
