The fact that I've done some pretty dumb things in my life will likely be the least surprising thing you'll hear today. That's why I'm sympathetic to those who like to mess around with laser pointers, but the FBI has issued a stern warning about how that could lead to dire consequences.

The FBI in Chicago just issued a very terse warning about how they have a zero tolerance policy when it comes to laser pointers being directed at aircraft. They say there has been "a significant and dangerous increase in laser strike events over the past two years in the Chicagoland area".

“The FBI has zero tolerance for anyone who is unlawfully using lasers and attempting to put lives at risk on the ground or in the sky,” said FBI Chicago Special Agent in Charge Ryan Whalen. “We are proud to work with our dedicated partners to ensure that criminals are quickly apprehended and held fully accountable under the federal felony statutes.”

Why are laser pointers dangerous to pilots?

A laser beam expands as it ascends into the sky. What appears like a small pin-point light on the ground can result in a blinding light the size of a watermelon by the time it reaches a plane. This is especially problematic at night when a pilot's eyes are dark-adapted and sensitive. A laser that reaches a pilots eyes at night can cause temporary blindness and also after-images that can affect their vision longer term. The incidents the FBI in Chicago are talking about often happen during takeoffs and landings which is a critical time where a pilot being disoriented can result in a tragic crash that can cost lives.

If you know of individuals that are using laser pointers in this way, you can call 1-800-CALL-FBI or submit an anonymous tip online.
