James has already pointed to this speech by Uncle Fetzer, where he essentially endorses Judy Wood's Deathstar theory, that some sort of satellite-mounted raygun brought down the World Trade Center. Now that's pretty kooky, but at least you can fantasize that it's true.
But how do these nutbars continue to make their nutty claim about the Bathtub? Fetzer says (at 3:54)
"The Bathtub was not seriously damaged. That's stunning. Think about what would have happened if the Bathtub had been seriously damaged. You would have had this massive flooding of lower Manhattan."
As most of us know from playing in the sand at the seashore, if you are close to a body of water and you start digging, you will pretty quickly hit water. Since the World Trade Center was built close to water, the basement levels had to be surrounded by what Judy Wood calls the bathtub; an impervious concrete wall that keeps out the water. This is what she claims was undamaged. Now, first of all it is obvious that it was damaged to some extent. But more important, even if it had been destroyed, there would not have been "this massive flooding of lower Manhattan." The water would have risen in the hole until it reached sea level, which is quite obviously several feet lower than ground level. Manhattan is not like the Zuyder Zee in Holland where the land is actually below sea level, and held back with dykes and seawalls.
And this guy claims to be a scientist?
