Make your own UAV

Amateur engineers can build their own UAVs similar to what NASA or the military is creating. This success mirrors the innovation in computing during the 1970s.

Son of Concord to offer commercial flights at 3400mph

The revolutionary plane called A2 will fly at a top speed of 3,400mph and should be able to carry 300 passengers. To reach Mach 3 the plane initially generates thrust through engines similar to those used in conventional jet aircraft. Beyond Mach 3, the super-heated air is pre-cooled before it enters the turbines, preventing the engines from melting. The plane has a minimal carbon footprint because it is fueled by liquid hydrogen, producing only water vapor and nitrous oxide as exhaust.

The A2 will cruise at an altitude of 100,000ft. A ticket from Europe to Australia is estimated to cost around $4000.
