British engineers unveiled plans Tuesday for a hypersonic jet which could fly from Europe to Australia in less than five hours. The A2 plane, designed by engineering company Reaction Engines based in Oxfordshire, southern England, could carry 300 passengers at a top speed of almost 4,000 mph (6,400 kmh), five times the speed of sound.Photo: AFP
