I have never watched A-10's do touch and go's, but I would likely enjoy it. Back in 1979-1981, I was serving in the US Army at Fort Hood, TX. My MOS was 16P, Short Range Air Defense Artillery. I was a gunner on a Chaparral Missile system. My job was to shoot down enemy aircraft, however, the US was not at war at that time. Still, we trained. Since we were short of enemy aircraft to work with, we used what was available, friendly aircraft. For those unfamiliar with Fort Hood, it is one of the largest Army bases in the US, with a very large "impact" area, used by all branches for live fire training, aircraft included. Fort Hood was also home to the First Air Cavalry (Cobra attack helicopters). It was rare to not see something flying over Fort Hood! The variety of "targets" was spectacular - T-38's, F-4's, A-7's, A-10's, F-105's, F-14's, OV-1B's, OV-10's, UH-1's, AH-1's, CH-47's, OH-58's, C-130's and even an occasional C-5!
Using a dummy missile with a live IR seeker section, we were able to acquire and track targets as they flew over or went through their attack runs. Of all the aircraft we saw, we all agreed that one presented the most challenge to us. That one was the A-10. While not as fast as some of the others, it was far more agile, zigzagging to the point of being almost impossible to get missile lock on it. None of the others making attack runs were difficult for us to track. I was always happy that those planes were on our side!
