IIRC, firing the GAU-8 reduces the airspeed of the A-10. Imagine what firing 21 of them, sideways, would do, even to a big bird like the C-5.

No, this is just a rumor, the mass that they're firing out of the gun (couple hundred KG, maybe, in a few seconds) is nothing compared to the mass and velocity of the A10, so it doesn't slow down at all (maybe on the microsecond level, but nothing measurable by normal means )

Now, a big gun, say the 105 mounted on an AC130, may skew the plane sideways a bit, but wouldn't affect it's forward velocity either I imagine.
