I have a B-in-law who when I 1st met him was a ballistics physicist at 
the Aberdeen Proving Grounds. It runs in that thread of the family as 
his mother and one daughter are in, were in, a similar business. He 
later went on to space junk. I never did ask him much as to what he did 
there with cannons... though I am curious what shooting projectiles 
means in the last 30 years of the 20th century. I would say that as much 
as effort went into the science of building a fort their would be as 
much curious energy and science put to holing one.
