I’m at Farnborough International Airshow, looking down into the cockpit of the jet fighter of the future – and it’s empty. Instead of the usual rows of displays, buttons and switches, there’s nothing but a seat and a stick. 

Everything else is virtual, and housed within a helmet that heavily, but comfortably, encases the pilot’s head, showing your surroundings (simulated, in this case) in colorful full HD.
