@1:32who can post a picture, funny, strange, and/or random, which answers this question:
'WHAT is the sound of one hand clapping?'
The average recoil force of the GAU-8/A is 10,000 pounds-force (45 kN), which is slightly more than the output of one of the A-10's two TF34 engines (9,065 lbf / 40.3 kN each). While this recoil force is significant, in practice a cannon fire burst only slows the aircraft a few miles per hour in level flight
Some people say that they would hit with the fist of an angry god - well, I don't have one of those.... but when I smashed, it'd be a smashing like unto:
