Al Frickey [pseud.], 'Stealth — and Beyond,' Gung-Ho (February 1988), 41. The article makes a number of dubious claims — that the July 1986 crash near Bakersfield did not involve a stealth fighter, but rather a plane 'that was more conventional, but just as black,' or that the stealth fighter would be deployed in flight from a C-5. The rear doors would open, the stealth fighter would be extended out into the airflow on a hook, the wings would unfold, and it would be released. Once the mission was completed, another C-5 would make a midair pickup. This article also claimed the D-21 had a top speed of Mach 5. It also referred to Aurora and the possibility of captured flying saucers at Groom Lake.
