Laser speed sensor promises safer air travel (3:14)

Oct. 17 - Australian engineers, motivated by the 2009 crash of Air France Flight 447, have come up with a laser speed sensor system for aircraft that they say will reduce the possibility of similar disasters. The Air France crash off the coast of Brazil was triggered by the icing of speed sensors on the exterior of the plane and, while the laser system is not designed as a replacement, its developers say it will greatly enhance flight safety.
