Reaction Engines’ Mach 5 engine is just the tip of the new aerospace boom

Imagine a hypersonic passenger aircraft that would cut the journey time between London and New York to around two hours. At Mach 5, or five times the speed of sound, the aircraft would complete a trip across the Atlantic in around 120 minutes. Mach 5 is more than twice as fast as the cruising speed of Concorde and over 50% faster than the SR-71 Blackbird – the world’s fastest jet-engine powered aircraft. A flight across the Pacific would take roughly three hours. Flight times from London to Sydney could be 80% shorter. Who needs Elon Musk?
