EqualSlash writes "High-power laser pointers available for cheap are increasingly finding abuse as the ultimate long-distance weapons of pranksters and vandals. The Federal Aviation Administration says laser events aimed on planes have nearly doubled in the last year, leaping from 1,527 in 2009 to 2,836 in 2010. The highest number of incidents was reported at Los Angeles International Airport, which recorded 102 in 2010. Lasers pointed at cockpits can temporarily blind pilots, forcing them to give up control of an aircraft to their co-pilot or abort a take-off/landing. In March of 2008, unidentified individuals wielding four green laser pointers launched a coordinated attack on six incoming planes at Sydney Airport, which resulted in a ban on all laser pointers in the state of New South Wales."
