Again, my condolences to our devastated fellow Americans in New Orleans and surrounding parishes, and along the Gulf coasts of Mississippi and Alabama.
For the record, I do understand that because the storm surge is for the most part not laterally constrained, it's able to flow around certain obstacles in a way that an aircraft carrier could not.
In your haste you took a cubic of foot of water to equal 1 lb. It equals something around 65. The carrier can't weigh more than the water it dispaces, roughly 35 ft X 100 ft X 1000 ft.
Your numbers are off. You converted 1 cubic foot to 1 lb. It is around 65 lb.
Ship can't weigh more than it displaces. Roughly 35'X120'X1000'.
Thus you went way under the actual weight by x65.
Thanks for the beautiful picture!
