Let’s start this story off with the fastest aircraft ever developed by the American military. The Falcon Hypersonic Test Vehicle 2 is an experimental rocket glider piloted by remote control that is designed to push the envelope of faster-than-sound travel to the tune of Mach 22. The idea is to create a craft that can reach any target in the world and deliver an explosive strike within a single hour, and to do so DARPA has developed a tough, lightweight glider. So far, test flights haven’t gone as planned, but the program is still in development.
