We have one of the shells form this thing in Annapolis proving grounds visitor area. Seeing that shell in person made me realize, i could indeed fire fat people out of a cannon. I'd just need a solid surface under them so they dont gum up the works. Though, I'm sure the blast pressure would make them a bag of mush if they didnt outright explode in the barrel. We need some science... Particularly, i'd like to move to the experimentation phase of the above hypothesis.
