Supersonic Aerospace International (SAI), based in Nevada, USA, is developing a supersonic aircraft called Quiet Supersonic Transport (QSST). it'll be ready for flight by 2014, and deliverable to customers by 2016.

It promises to be 100 times quieter than the Concorde with a range of over 4000 nautical! miles and a top speed of Mach 1.8, or 1,188 miles per hour.
