The Czech Airline Pilots Association has revealed a worrying development in
the Czech Republic: the escalation of laser device attacks from the ground
on civilian planes. In 2009, unknown perpetrators aimed Level 3 lasers at
airplane windscreens, temporarily blinding pilots for at least for a couple
of seconds. Devices capable of such mischief, which can cause permanent eye
damage, are apparently readily available without restrictions, one reason
the pilots are seeking tougher legislation.
