Let’s take a look at what was to be the ultimate high speed, high altitude and last manned strategic bomber: The XB-70 Valkyrie. An aircraft which still looks futuristic even today, the Valkyrie was a Mach 3 bomber which flew at 70,000 feet, rode its own shock wave – and almost wasn’t built. Changing technologies and advancements in weapons systems nearly doomed this aircraft to just a concept design in aviation.

Today we will take a look at the Valkyrie’s story, and the legacy it leaves behind.
