No wonder Obama tried to get rid of it.
Got to get up and personal with one in 2018 at the Minot AFB air show. They had one parked on base with a couple airmen to answer questions. You could walk up and touch the gun. LOL, way bigger than my daughters hand. Impressive piece of engineering.
Of course it is true. They didn't repeal F=MA. It's just that the rearward force against the fuselage from the cannon firing is proportionally small enough that the velocity reduction isn't noticed. It is equivalent to the drag force operating on the aircraft.
It would make a good physics problem for high school students to solve. "How much does the A-10 slow down when the GAU-8 Avenger is firing at a rate of 1,800 rounds per minute?"
Instead they get asked to solve "If Heather has two mommies, and each of them has two brothers, and one of those brothers has another man for a 'roommate,' how many uncles does Heather have?"
