Rides an air scooter straight up the wall and, at the apex of his ascension, turns around and races down on foot Azula spots him and, intending to intercept him, send a blue fire blast at him at close range, Aang speeds past it, missing the blast by a fraction of a second, and slams down with an air impact on the rock spike, driving it deep. The impact causes the compromised braces to snap and the excess slurry bursts out of the machine., Broken down, the drill is left jammed partially in the Outer Wall.
