A handout photo taken and received on May 18, 2016, shows the launch of an experimental rocket on trial which reached an altitude of 278 kilometres and a target speed of Mach 7.5 in the latest successful test of hypersonic technology in the Australian desert. A joint US-Australian military research team is running a series of 10 trials at the world's largest land testing range, Woomera in South Australia, developing the scramjet, a supersonic combustion engine that uses oxygen from the atmosphere for fuel, making it lighter and faster than fuel-carrying rockets. / AFP PHOTO / ADF / CPL Bill Solomou / ----EDITORS NOTE ----RESTRICTED TO EDITORIAL USE MANDATORY CREDIT " AFP PHOTO / AUSTRALIAN DEFENCE" NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
