It's amazing the power with which those boolets hit the ground. I'm not 100% convinced it was an A-10, however. I've never been standing out in the field when an A-10 flew over and shot it's big gun, but I have stood around and watched an FA-18 do so. The rate of fire of the FA-18's M61A2 20mm is higher than that of the A-10, and the gun in that video (in which we never see the plane) sounds like the M61... Either way, sort of impressive!
