I had posted about this case last April. From Ars Technica:
“Bored” California man sentenced to nearly two years for laser strike
On Monday, a federal court in Central California sentenced a 26-year-old to one year and nine months in prison for firing two different laser pointers at a Kern County Sheriff’s Office helicopter over a six month period in 2013.
The man, Brett Lee Scott of Buttonwillow, took a plea deal with federal prosecutors according to a May 5, 2014 court filing. Scott explained his actions by saying that he was “bored.”
It may seem like a silly thing, but laser strikes against planes, helicopters, and other aerial vehicles have become an increasing epidemic nationwide. Since the FBI began keeping track in 2005, there have been more than 17,000 laser strikes—one-fifth (3,960) in 2013 alone. During the first three months of 2014, the FBI reported an average of 9.5 incidents daily.
They are sending a message and it is a good one. Fifteen years ago, this would be an annoyance. These days, laser technology has gotten cheap and powerful enough that permanent retinal scaring can result in a moment. Bad enough on the ground but horrible for a pilot.
Here is one horrible example - a Russian Rave from 2008. 12 completely blind with 49 injured with as much as 80% loss of vision. Recovery is impossible.
