We've been told in the past that our mean, hate-filled looks could kill, but we never took that literally. Now, if Britain's BAE Systems has its way, that phrase could seriously have a whole new meaning. The company has developed an RAF helmet that will allow pilots to deploy and steer their weapons by turning their heads. It all sounds incredibly horrifying and futuristic, of course, but the technology which enables the new gadget is pretty intense, as well. The helmet is fitted with an optical head tracker, with targets popping up in the visor, which provides a supposedly highly accurate missile fire with low latency, at any altitude. The system has been extensively tested on the Eurofighter Typhoon, but is modular in styling so that it can be fitted to many systems. There's no word on when this tech will see actual action, but we have our reservations about it, so we hope they take their time.
