I met Denys Overholser while an engineer with GE Aircraft Engines in Cincinnati, Ohio. He and my boss, Don Foreman (now deceased) were good friends. Don was also somewhat of a stealth pioneer.
I also worked with the original F-117 wing commander, Colonel Robert Jackson while at General Dynamics - though I didn't know his background at the time (He had retired a few years earlier). I didn't find out his connection with the F-117 until The History Channel did a weeklong series on Stealth Technology (about 10-12 years ago) and interviewed him. He was also a former Thunderbird Pilot. Turns out I had a brochure that I had save from an airshow when I was about 8 years old. It had his picture in it. That brought a lot of smiles when I passed it around the office.
Also, the article mentions a test range in White Sands. That was likely the RATSCAT facility near Alamogordo.
RATSCAT. Spent 3 weeks there back in the 80s. Clearest night sky I've ever seen.
I was in ROTC summer camp at Holloman AFB in 1976. We got to visit the RATSCAT facility. As I remember, I saw models of B-1B aircraft among others. There was another Flight from our ROTC camp that went to visit the RATSCAT on a different day - I was told that when they showed up, they had to wait in their bus for a while as technicians scrambled to cover up some models. I believe there was a scheduling mistake. Only years later did it occur to me that they were testing early models of Stealth designs at that facility while I was there.
