Is there a video game-playing kid who wouldn’t buy a consumer version of this that works with PS3 and Xbox? It would make million$.

This is how the next generation of RAF fighter pilots will look. And with piercing green eyes staring out from behind the visor, it’s no surprise that the helmet has been compared to Arnold Schwarzenegger’s killer robot in The Terminator.

Pilots flying the F-35 Joint Strike Fighter will have an astonishing array of technology encasing their heads – enabling them to see right through their own aircraft fuselage to the ground below.

A series of cameras on the outside of the stealth warplane feed high-resolution images into the helmet, including infra-red images at night, which are then projected on to the inside of the pilot’s visor. Special sensors inside the cockpit track the movement of the helmet, so that when the pilot turns his head his view of the skies or ground outside changes accordingly. When he looks down he sees not his own feet on the cockpit floor but the ground below, slipping past at hundreds of miles per hour.

On-board computers also feed in essential flight and combat data on to the display, as well as superimposing target symbols to locate enemy and friendly aircraft or ground targets, even if they are too far away to see with the naked eye.
