In brief: Air laser pests face five years
Pointing hand-held lasers at aircraft would become a crime punishable by up to five years in prison under new legislation in the US.
Democratic senator Sheldon Whitehouse, who sponsored the amendment, said he was responding to a surge in incidents in which people had pointed powerful lasers, capable of temporarily blinding pilots, at aircraft.
The Federal Aviation Administration said the number of incidents in which people targeted planes and helicopters nearly doubled last year, from 1,527 in 2009 to 2,836 in 2010.
