Salute!
Given the time frame, I would think the Migs were the biggie, although the 117's had not moved to Holloman yet. The Migs had to fly in daylight for Constant Peg and Red Flag, unlike the 117.
My briefings at Red Flag always included the option to land at a "suitable, nearest: strip that we could see. In other words, don't fly over Groom Lake trying to reach Nellis. Tonopah was at the NW of the Red Flag ranges, but it was easier to reach than Groom Lake, and I flew a few missions just south of there.
Great war story.
