A hypersonic aircraft is being developed by a Texas-based company called Venus Aerospace. They have already created a functional engine for the project, and based on preliminary tests, they expect the plane to achieve speeds of up to 7,402.9 km/h. This would make it capable of flying at six times the speed of sound and three times faster than the famed Concorde supersonic airliner. With this speed, a journey from London to New York could be completed in under an hour.
