Yes delta wing aircraft have some real nasty low speed habits and stall recovery requires a lot of altitude. They glide like rocks.

And yet an unmanned F-106 made a "safe" landing - see link to USAF museum.

The aircraft on display (S/N 58-0787) was involved in an unusual incident. During a training mission from Malmstrom AFB on February 2, 1970, it suddenly entered an uncontrollable flat spin forcing the pilot to eject. Unpiloted, the aircraft recovered on its own, apparently due to the balance and configuration changes caused by the ejection, and miraculously made a gentle belly landing in a snow-covered field near Big Sandy, Montana. After minor repairs, the aircraft was returned to service. It last served with the 49th Fighter Interceptor Squadron before being brought to the Museum in August 1986.

The 106 was similar to but much better than the 102. Both were used as Intercepters in North American Air Defense. As far as the story you mentioned goes (knew about it). And remember that people have survived a 10,000 ft fall without a parachute, but they never recommend that others try it. Flat spins are seldom recovered from in any plane. Flat spins usually stop upon impact with terra firma.
