This has been a problem at airports ever since these laser pens became widely available. There no way to catch whoever did it unless someone witnesses them doing it and goes to the police - the beam could be coming from absolutely anywhere in a fairly wide radius. There's no way to trace exactly where it came from.

Wouldn't that be determined by the size and the power of the laser, could something powered by an AAA battery reach 36,000 ft?
