It's a growing menace. The FBI is highlighting the risks posed by laser strikes on aircraft.
The agency wants to crack down on those that aim laser pointers at planes and helicopters and temporarily blind pilots.
Robert Hamilton has been struck, he says it's like being in a dark room and then having someone set off a flash camera right in your face.
Only he's landing, with lives at stake. Special Agent Monica Miller says there were 3,900 strikes across the country last year -- 25 in Sacramento -- and now.
"There's a $10,000 reward for those vandals, so to speak," Miller said.
Penalties are real, and harsh.
Conviction can lead to up to five years in prison and a $250,000 fine," U.S. Attorney Benjamin Wagner said.
Wagner has prosecuted two suspects last month.
