NASA QueSST Passenger Jet
When the Concorde called it quits in 2003, it took with it the only supersonic travel option we had. An unlikely group is trying to build a new alternative. The NASA QueSST Passenger Jet is based on Quiet Supersonic Technology (hence the name), and would create a sound more like a heartbeat than the traditional, house-shaking boom we're accustomed to while still getting you from point A to point B with remarkable speed. There are no details yet on how many passengers the aircraft might hold, or how high it might fly, but we do know that a team comprised of specialists from Lockheed Martin, GE Aviation, and Tri Models Inc. are working on it, and that they hope to start their initial flight campaign in 2020.
