A remote-controlled plane powered from the ground by a laser beam has been tested by Nasa. In what is thought to be an aviation first, the development could lead to the creation of aircraft that do not need to carry on-board fuel.
The 300-gram (11-ounce) plane, with a 1.5 metre (five foot) wingspan was launched from a platform and a laser then began to power its engine.
The plane stayed aloft until the laser was cut off, and then the aircraft glided into a landing.http://news.bbc.co.uk/2/hi/americas/3182744.stm
