Boom Technology says it is using modern engines and materials to develop a supersonic passenger jet that can cruise at Mach 2.2 (1,675 mph, 2,700 km/h), with prices starting at US$5,000 for a return ticket between London and New York.

When the two Concorde fleets were grounded in 2003, aviation took a giant step backwards. However, it may not be a permanent setback with NASA starting development on a new supersonic X-plane and various companies testing the supersonic waters. This would be encouraging if it weren't for the fact that the Concorde was anything but a bargain. It may have been able to carry up to 128 passengers at Mach 2 (1,500 mph, 2,450 km/h), but the average round trip price from London to New York was $12,000.

With headquarters at Centennial Airport near Denver, Boom Technology believes that it can build a new supersonic passenger jet in just a few years that will not only be faster, but also cheaper than its predecessor. The finished product is projected to carry 40 passengers in two single-seat rows of standard first-class seats at a cruising altitude of 60,000 ft (18,000 m) and a speed of Mach 2.2.

In a report in Bloomberg Business, Boom said that it's only been in the last 10 years that the technology became available to make a Concorde replacement practical. Thanks to new advances in aerodynamics, composites, engines, wind tunnels, and software, Boom believes that it's possible to make a plane that can fly from London to New York in 3.6 hours at a cost of $5,000 for round trip.
