An experimental radio-controlled model aircraft is seen here in flight powered only by light energy beamed to it by a spotlight. Researchers from NASA’s Marshall Space Flight Center, Huntsville, AL, and Dryden Flight Research Center, Edwards, CA, and the University of Alabama in Huntsville have flight-demonstrated a small-scale aircraft that flies solely by means of propulsive power from an invisible, ground-based infrared laser.August 1, 2002NASA Photo / Tom Tschida› Power Beaming Project Description
