What was the biggest and most effective ballistic weapon for an aircraft in
WW2.
I realize that some aircraft carried 75mm cannon - the B25 iirc and the
Germans probably shoehorned an 88 into one of their fighter bombers - but
what was the one that was most effective as opposed to being largely
ineffectual and being better replaced with a smaller caliber.
My guess would be the Mosquito's 57mm anti-ship gun.
