A guy just got 30 (well deserved) months in prison for shining a laser at an aircraft.
Lasers and aircraft is a serious issue. Lasers can temporarily or permanently (depending upon laser strength) blind a person. A blind pilot cannot fly, so pointing lasers at aircraft is roughly equivalent to walking around with a loaded firearm and sweeping people with the safety off and your finger on the trigger - it is unsafe, malicious/negligent, and could easily lead to someone dying (it also violates every firearms safety rule ever). Pointing a laser at aircraft is either reckless endangerment or attempted murder.
