A firing aircraft feeling

A friend of mine asked me this question after watching me browsing A-10 photos in internet at work. He said: “I wonder how it feels in the plane when it is firing”. Well, I don’t know the answer but bet one of you does. So, how does it feel in the plane when a lot of ammo comes out of it?
P.S. The question was not exclusively specific to A-10. Any other aircraft experiences will be appreciated.

I’ve heard that A-10 pilots liken it to crashing through a long, solid brick wall.

not the answer…but I “heard” and “saw” up close and personal !


thank goodness for the “search”…I almost posted them all again…'happens at age 59 !!
