That's why Transport Canada is concerned about a significant spike in the number of times that happens these days.
Last year in B.C., there were 80 reported incidents of lasers being aimed at planes.
That is a 300 per cent increase from five years ago when the reported number was 26.
As of the second week of 2015, there have already been a pair of incidents at Vancouver International Airport.
One involved an Air Canada Jazz plane and the other a Helijet aircraft.
Anyone found guilty of pointing a laser at plane in the air could face $100,000 fine or up to five years in jail.
