Therefore, the comparison to the damage at the twin towers, is not valid. Yes, such a device could do damage to the ship, it could make a mess, but it could not kill two to three thousand people, just because it would not be in a place where that kind of population density would likely be. The Texas City, Texas explosion in 1947 of first one ship and then a second, killed almost 600 hundred people and injured almost 4000. It is said that if the same thing happened in the same location today, the dead toll would be in the 10's of thousands.
