You don’t often see models of the SR-71 Blackbird, one of the most advanced spy planes used by the CIA. And you definitely don’t see 18-foot-long model jets! In Israel last week, the world’s largest scale-model of a SR-71 Blackbird took flight. Built over 5 years by Gilad Olinki and flown by Ofir Babish, the 1/6-scale jet weighs 176 pounds and is powered by two turbines. A Weatronic radio provides the guidance. Nicely done!
