If you look a little closer, they're using mirrors and the light is coming from below. It's why they stay hovering over a particular spot. Having a
light that bright on a quad that size would drain the battery too quick otherwise. Would be cool if a light that bright was powered by a battery on
the quad-rotor, but the tech still doesn't seem to be there yet on that scale.
Yet following the same technique they used, and with some of the laser kits that are out there now, it would be fairly easy to pull off some hoaxes on
an unaware public. Just needs more planning and setup than simpy flying an R/C craft around.
