Hm... I guess I did mention that it's 40 kN per engine, and 2 engines...

Depends on how strong the aerodynamic drag at minimum speed is. If it was
equivalent to ca. 35 kN, that would come close enough to stopping the plane for
practical purposes ;P (though I doubt it; the actual slowing down of the plane
seen when firing is most likely just due to the pilot not bothering to readjust
the throttle accordingly; I bet they're not flying anywhere near 100% power when
in a 30 degrees attack dive...)

Is that "dakka" as in "rat-tat-tat"?
But these things don't go "rat-tat-tat", nor "dakka dakka" - they're more like a
loud, high-pitched humming at 3900 Hz (something like b'''' for the musicians
out there)...

Impressive? Beyond doubt. Beautiful? Uh... no, not really :P

Yeah, that shows pretty well why the thing is not called a "gun" but a
"cannon"...
That's basically all the A-10's purpose: Bring that thing up into the air, aim
it at one of the bad guys, and play that song in b''''. Yeah, and drop a few
bombs while you're there anyway.
