You must have an appreciation for the US military's penchant for writing between the lines. Basically, this guy has been cast out by the Air Force. He'll never fly anything again and the FAA will probably pull his civilian endorsements as well. This is as far as the USAF can go; at the end of the day, they armed him, gave him a commission and let him fly. They've done evrything they could to hammer him yet save themselves from more liability. Anything more would call into question the judgment of his superiors in allowing him to get into the cockpit in the first place.
I must add, as a partisan for Marine Corps CAS doctrine, that the Air Farce has never been particularly good at that mission. They fly too high and too fast for effective support. "Low and Slow" is the way to go, as it were. Recall also that the AF tried for years to delay, forestall, cancel, kill and abandon the A-10. They only kept it to save their turf from the Army. Sickening, actually. Fifty-seven years after they were mistakenly given birth, and they still haven't realized that they are, at best, a supporting arm. Not a very good one, at that. In comparison, all USMC officers are trained as riflemen first. Navy and Marine Corps officers serve as ground-based FACs in the ANGLICO and infantry battalion fire support coordination center. Air Force pilots don't serve as FACs on the ground, as far as I know. They fly FAC missions from F-16s! How? I don't know. Not well.
If ANGLICO sailors and Marines had been with your lads, this never would have happened. If it'd been AV-8B or F/A-18 above, this could've been avoided. I apologize for my country's inept air force.
