Thanks, I've landed at and tied my airplane down at the commercial Bosie airport on the south east side of Boise, is that the same air field where the ANG A 10 are?
I was privilege to see a live fire demonstration at Edwards AFB by two A10s back in the late 1970s or maybe even in early 1980s on one of their open house days, they shot around 300 to maybe as high as 500 rounds into a target out on the dry lake near enough for us spectators to see
They made several firing passes each, two planes, and it seemed that when they fire that canon the airplane stood still or even look like it was backing up
BRRRRUp, BRRRUp and a whole lot of dirt exploded and flew up into the air out there in the dry lake
That weapon is infantry mans best friend
