Boom, the new Concorde

This is Boom. Boom is a prototype for a new supersonic passenger aeroplane that will be able to fly New York to London in 3.5 hours, slightly quicker than Concorde used to. But that's not the clever bit. The smart thing about Boom is that it uses existing technologies to keep costs low, and the business model is based on flights being about the same price as Business Class is today. Apparently Boom is already in development and test flights are planned for late 2017...
