Supersonic Aerospace International has designs for the Quiet Supersonic Transport (QSST), a business plane that could travel at supersonic speed with a minimal sonic boom. The Lockheed Martin "Skunk Works" design would allow planes to fly between Mach 1.6 and Mach 1.8 (almost 1,200 miles per hour) over populated land areas--twice the speed of current airlines. A flight from New York to Los Angeles could take as little as 2 hours and 15 minutes, the company says.
The first test flight is expected in 2011 and the first commercial flights are slated for 2013. SAI was founded in 2000 by J. Michael Paulson, son of Gulfstream founder and former CEO Allen Paulson.
