Lockheed Martin's Green Supersonic Machine

An artist's impression of Nasa and Lockheed Martin's Green Supersonic Machine, capable of supersonic, sub-orbital space flight. 

Planes travelling at five times the speed of sound and passenger aircraft flying in formation could come to pass in the last part of this century, according to a report by the Institution of Mechanical Engineers.
