Boom Technology, an aviation startup, unveiled today a subscale prototype of a supersonic passenger jet that aims to be the next generation Concorde. The XB-1 Supersonic Demonstrator, nicknamed "Baby Boom," won't take flight until late 2017, but Boom unveiled the prototype to a group of aviation and aerospace executives at Centennial Airport in Denver.

The XB-1 is a one-third scale version of the full production model that Boom hopes to have ready for passengers by 2020. The prototype only has room for the pilot, while the commercial-ready version will eventually hold up to 44 passengers. The startup claims its vehicles will be able to travel from from New York to London — normally a 7-hour flight — in just 3.5 hours, or LA to Sydney — typically a 15-hour trip — in 6 hours and 45 minutes. Tickets will cost the "affordable" price of $5,000 per seat.
