Dunno about that... with the pumping stations running at full capacity, as they would be if it weren't for something like a cat 5 'cane, it would be little more than an inconvenience. An attack coordinated enough to take out enough levees as well as enough of the pumping infrastructure to actually flood the city could probably do something much more significant in another place like NYC or LA..mike_s:For what I can see, Al Qaeda could have driven a large ski boat up to any of the levee's with enough explosives to have submerged the city with a single explosion.
If they had done it with several teams like they did on Sept 11th, then it would
have caused more damange than the WTC attack with a much more low-tech attack.
