After the 747 test flights, Boeing re-registered the aircraft as N1352B in July 1970 to explore missions beyond its original design specifications. These missions were primarily military, including using N1352B as a refuelling tanker for the Lockheed SR-71 Blackbird and the Boeing B-52 Stratofortress. Unfortunately, the idea of using the Boeing ...
