The FBI is warning that aiming laser pointers at flying aircraft is a serious offense punishable by years in jail and thousands of dollars in fines.
At a press conference Monday, St. Louis officials said that pilots typically report several laser strikes per day.
Doug Reinholz is a helicopter pilot with the St. Louis Police Department. He says the light from laser pointers can be blinding to pilots, particularly at night.
"It's equivalent to like a flash of a camera if you were in a pitch black car at night," Reinholz said.
