Ed ~ By opening the laser pointing device a small power control screw can be located and adjusted to decrease the power. However a hacked illegal laser will probably still require a permit.

Gregor said he didn't know why people point lasers at airplanes, but he noted that some of those arrested in the incidents had been consuming alcohol and others were teenagers. He said some contacts could also be accidents caused by amateur astronomers who use lasers to help them aim their telescopes or to point out constellations.
