Boom Technology, a US-based supersonic transport startup, is developing a supersonic jet in partnership with Japan Airlines that will fly from NY to London in less than 3.5 hours. The new jet, named Overture, is expected to be in service for passenger flights as soon as 2025-2027.  The reappearance of supersonic jets has the potential to transform the marketplace for time-critical air freight carriers and for courier giants such as Fedex and DHL, by reducing the transit time as well as the environmental impact of freighter aircraft.  Boom Technology is exploring ways to improve on the Concord jet by using a new technology being developed by Prometheus, for producing aviation fuel  which is converted from CO2 emissions in the atmosphere into liquid hydrocarbon and then transformed into aviation fuel. As a result of developments in propulsion technologies, the new jet is expected to fly at speeds in excess of Mach 2.2 without the use of afterburners, reducing the noise level and environmental damage associated with the first generation of supersonic aviation.   Read more about this exciting development here.
