"Aviation Week" describes Blackstar as a two-stage-to-orbit system, the first stage of which is a delta-winged supersonic jet (which "Aviation Week" referred to as the SR-3). Its description of SR-3 is similar to the North American B-70 Valkyrie Mach 3 strategic bomber, and to patents filed in the 1980s by Boeing. The ...
