A Boston based engineering firm Spike Aerospace have unveiled new Super Jet

Has anyone heard about the Supersonic Jet?

A Boston based engineering firm Spike Aerospace have unveiled plans to develop the Spike S-512. The supersonic jet will be a 12 – 18 seater jet designed for commercial use only and will be able to fly from New York to London in under 4 hours, that’s around half the time it takes now.

With an estimated cost of up to $US80 million per private jet – Spike developers have spent years honing their design and believe the aircraft could take off by late 2018.

Spike Aerospace is not the only company committing itself to offering supersonic flights, however. The Nevada-based company Aerion Corporation has submitted plans for the development of a private jet that could reach speeds of Mach 1.6, potentially carrying its first passengers by the end of the decade. HyperMach Aerospace Ltd, meanwhile, has proposed the development of SonicStar, a jet the company claims would reach Mach 4 (about 4200 km/h and approximately twice the speed of Concorde) and could speed from London to Sydney in an afternoon or from New York to London in about an hour. The firm estimates it could enter production in the 2020s.
