Art in the sky: check out these spectacular drone displays - Airline Ratings

The stunning aerial dance of UFO's that wowed audiences in Steven Speilberg's Close Encounters of the Third Kind has become a reality thanks to the drone. The small aerial vehicles may be a potential threat in some circumstances but they can be beautiful in others. A spectacular aerial art form continues to evolve as operators use lighted drones and computer algorithms to create animations in the sky.
