A Brisbane-based company is preparing to launch the Dart AE, a 3D-printed autonomous vehicle designed to travel at five times the speed of sound using scramjet engine technology. The 3.5-metre vehicle will launch from a NASA facility in West Virginia, reaching the edge of space before flying horizontally for approximately 10 minutes at speeds up to Mach 5. The successful test represents a significant step towards commercial supersonic aviation that could reduce travel time from Sydney to London to just two hours.
