Long flights could be annoying for many reasons but not anymore! With the hypersonic engine in development in Britain, air travel time can drop significantly. It is touted that air travel time from London to Sydney will be just four hours with the hypersonic planes. It might sound something from a sci-fi movie, but it is a new tech that can redefine the future of air travel.
Well, British firm Reaction Engines is working on a new engine, which can propel an aircraft to Mach 5.4, which is over twice the speed of Mach 25 in space and five times the speed of sound. This means that the engine can propel an aircraft at a top speed of around 4,143 miles her hour.
