Lasers were aimed at more than 20 aircraft across the country Wednesday night, including two over Kentucky cities, and reports of such incidents are up 38 percent over 2014, according to the Federal Aviation Administration.
Shining lasers at aircraft is a federal crime because it can harm pilots and passengers, according to an FAA Facebook post.
The lasers can cause eye damage and temporary blindness, and they can distract pilots.
The cities where the "laser strikes" occurred Wednesday include the Kentucky cities of Covington and Danville, plus New York and Jamestown, N.Y.; Newark, N.J.; Dallas; Detroit; Salt Lake City; Albuquerque, N.M.; Oakland, Palm Springs, Ontario, Los Angles and Sacramento, Calif.; St. Petersburg, Fla.; Springfield, Ill.; and San Juan, Puerto Rico.
Never miss a local story.
None of the pilots reported injuries as a result of the laser, according to the FAA.
As of Oct. 16, this year's total number of laser incidents with aircraft in the United States was 5,352, according to the FAA. In 2014, 3,892 laser incidents were reported.
