FWIW, Robert S. Johnson (well, Martin Caidin in RSJ's name*)
claimed that on the occasion of his first kill, the noise of all 8 of
the Jug's fifties firing together scared (or at least startled) him to
the point that he let go of the trigger. Up 'til that point, he'd only
fired one at a time, at towed socks.

*note that Johnson left that part of the tale in when he revised
and re-released Thunderbolt!

I can't imagine that, while firing all eight of those .50's in a P-47, that the
whole plane wasn't shaking....much less just the stick. Anybody with shooting
experience in that plane care to detail their experience?

Never flew the P-47 but firing the six guns in the Mustang created a
lot of noise but little if any vibration. Certainly didn't shake the
stick.
