US aircraft manufacturers along with NASA are working on a plane made from composite materials to make it light and fitted with powerful engines capable of taking it to a cruising speed of 2,500 mph! In comparison, Concorde’s cruising speed was 1,350 mph, so it is clear that should such a plane make into the air, it is going to cut the time taken to travel around the world by a massive amount. In fact, currently it takes over twenty hours to fly from London to Sydney; the new craft in comparison will make the same journey in around four hours. The good news is that the US manufacturers are expected to be showing their prototypes off next month at the Farnborough Air Show.
According to a Gulfsteam engineer, he said that;
The fact that the big boys are all close confirms industry rumours that a new generation of supersonic planes is now, finally, within reach.
