(CNN) — The news broke last September that a California start-up was working with the US Air Force on developing a supersonic plane which could be used as Air Force One.

Exosonic was handed a contract by the Presidential and Executive Airlift Directorate (PE) after impressing the military with its concept for a low-boom supersonic Mach 1.8 twinjet. .......................

Exosonic's plane boasts a 5,000-nautical-mile range and, thanks to boom-softening techniques, it should be able to fly overland at almost twice the speed of sound without upsetting residents down below.........................

Exosonic isn't the only aviation trailblazer to receive investment from the US Air Force.

Atlanta-based Hermeus Corporation is working on a hypersonic 20-seater that promises to deliver passengers from New York to London in 90 minutes.

Last year, it partnered with the US Air Force and PE to develop its Mach 5 craft in order to support the presidential and executive fleet, and this March Hermeus announced that it was teaming up with NASA too.
