Boron Nitride Nanotubes For Planes to Travel at Hypersonic Speed

In February of 1949, the V-2 rocket was the first hypersonic flight to reach a maximum speed of Mach 5. Despite this achievement, the re-entry of the V-2 rocket into the atmosphere caused the vehicle to burn completely, leaving only charred remnants to be found. Since this initial attempt at hypersonic travel, Researchers have continued to work towards making this phenomenon into a reality.
