I can see how blowing up the tunnel would flood the TUNNEL. However, how would it send floodwaters through Manhattan? Water, IIRC, seeks its own level. The tunnel is below the level of Manhattan streets, so how could water from there cause flooding? Why isn't Manhattan flooded right now anyway?

If the tunnel were breached, the level the water would seek is the level of the Hudson River's servoce.

Stories like this make we wonder just how bright some of these people are. Trying to flood Lower Manhattan by destroying the Holland Tunnel is about as realistic as trying to topple Mount Rushmore by getting every Muslim in the world to fart at the same time.

Jihadi physics.

They were going to put a dozen genies inside the explosives containers.

"One of two Pakistani nuclear engineers recently arrested on suspicion of passing nuclear secrets to the Taliban had earlier proposed to solve Pakistan's energy problems by harnessing the power of genies. He relied on the Islamic belief that God created man from clay, and angels and genies from fire; so this highly placed engineer proposed to capture the genies and extract their energy."

That's probably what the drive by media will say in their "Free terrorist hero's name here" defense. It wouldn't have worked like they thought, ergo it was nothing. Now on to our latest global warming disaster scenario.

The fact that it's a terrorist plot to attack NYC again will be conveniently forgotten. The fact that even if it succeeded in blowing up the Holland Tunnel but failed to flood Manhatten would still result in a gold mine of terror to the terrorists will never even have been thought of by the media.

You obviously don't understand modern global warming physics. Just the other day some Euro-scientists were describing how the decreasing water level in the Arctic is explained by water flowing uphill to the equator (we know from global warming theory that the ocean levels are rising).

Logic is not their strong point.

It said New York officials, according to sources, believed the plan could conceivably work with enough explosives placed in the middle of the tunnel.

But it added that some experts did not consider the plan feasible because the tunnel was protected by concrete and cast-iron steel and that even if the tunnel cracked, the Wall Street district would not flood because it was above the level of the river.

Some terrorists aren’t known for their smarts. They may have confused New York with New Orleans.

Must be that "Islamic tradition of scholarship" we keep hearing about. The principles are too advanced for us infidels to understand. ;)

Exactly. At first I thought a surge from the tunnel, but there would be no water in tunnel to surge.

Secondly, the amount of conventional explosives that would be needed to detonate in tunnel and then create a big enough wave would be far beyond what you could get into tunnel.

Several years ago downtown Chicago was 'flooded' when an old tunnel delivery system was breached under the river when working on the footings of a bridge, filling the basements, used and unused, of numerous buildings and interfering with power and other utilities. It was a huge mess and took quite awhile to fix. I don't know if NY has a similar system, but I presume most large cities have buried infrastructure that is supposed to stay dry. I have no idea of the vulnerabilities of NY's buried infrastructure and see no reason why such would necessarily correspond to a traffic tunnel. I hope the authorities in NY are more aware of their vulnerabilities, whatever they may be, than those in Chicago were at the time and also hope the bad guys remain ignorant of such!
