True Story: Back in 1986, I had a chance to visit the 162nd FS, an ANG unit at the Tucson International Airport who do a LOT of international F-16 training.
In addition to touring the offices and stuff, I had a chance to fly one of their sims. While it was a rigid platform type, the cockpit was real and the fidelity and fluidity of the graphics surrounding me (270° screen) was amazing. Before I hopped in the sim, I had the chance to try a “dumbed down” sim that was used for radar training and learning intercept geometry. It felt oddly familiar. I realized why when I saw the manufacturer’s badge on the side of one of the computers. The name was Spectrum Holobyte!
Short story, long: I think there’s a lot of consumer sim DNA sprinkled across military aviation applications.
