There were three squadrons of A-1s. Each squadron had twenty-something aircraft and there were always another handful from the other bases. As time went on, the numbers dwindled.

The "E" models were the 2 seaters. (Also referred to as a "fat face".) I liked them better too. I'm not sure why... maybe because us maintenance folks had a chance of getting a ride in the empty seat. I never did. The pilots didn't like the "fat faces" because they didn't fly as well as the single seaters. Also, since they flew most missions solo, the pilot didn't have a good view out the right side of the "fat faces"... that made them more vulnerable. I guess I wouldn't like that either when the bad guys started shooting at me from the blind side.
When I first got there, we were still using the PSP runway. While I was there Red Horse built the "real" runway that is still there. We used the parallel taxiway as the runway while they were building the new one. The new runway was (is) 8000 feet long. It even had arresting barriers at both ends. We started getting a lot more "visits" from the "fast movers" after the "real" runway was built. It was usually when they were shot-up and caught the barrier when they landed. As an "oh by the way", the "real" runway at NKP was the first ever entirely built by Red Horse. (At least I think that's true.) The runway they built is still in use today.
You can't really see it on Google Earth, but all of the PSP parking ramp has been ripped up. Although the laterite base is still there, the jungle is recovering most of that too. You can really see this in what used to be the A-26 parking area, but it's happening all over most of the rest of the flightline. I suspect that in another 20 years, no one will be able to tell we were ever there. Even today that's mostly true.
