Flying from Sydney to London in less than two hours could be a possibility within the next decade, research conducted by King’s College, London, in conjunction with the UK’s Royal Air Force shows.

Study participants had no lasting ill effects, and one lost consciousness as a result of brief periods of high G-force.
