Four more planes reportedly spotted lasers several thousand feet in the air over New York and New Tuesday night, bringing the total to 20 similar incidents in the last week. 
 
 Two planes west of Warwick, NY, an American flight 20 miles south of Newark and a Spirit Airlines plane 20 miles southwest of LaGuardia reported being illuminated by lasers, the Federal Aviation Administration confirmed to Fox News. The FAA notified law enforcement and is investigating. 
 
 Pointing a laser at a plane is a federal crime. The light can be disorienting for pilots approaching an airport. The number of reported laser incidents was up to nearly 2,000 through May 15, a record pace. 
 
 Pilots of 12 different planes reported laser sightings on Wednesday and four more pilots reported sightings on Thursday over New Jersey and Pennsylvania.

 At least six more flights over New York and New Jersey reported being illuminated by lasers Tuesday night, making 22 such incidents in recent weeks.In this recent rash of hits, six planes reported laser strikes including United Flight 1933 on approach to Newark."1933, we just got lasered from our 10 o'clock position," a pilot said.The FAA notified law enforcement about the reports, and the FAA is investigating. Below are the details on each flight:Like the previous rash of strikes, these laser hits were spread out from Newark to Warwick in Orange County, New York to LaGuardia in Queens. Twelve pilots reported spotting lasers Wednesday night, followed by at least another four pilots while flying over New Jersey and Pennsylvania Thursday night."We're they pointing it at you?" the tower asked"Directly pointing right at us. I saw the flash to left and out my head down," the pilot said.But as we reported in an investigation last year, laser strikes have plagued pilots flying in and out of our major airports ever since the hand-held devices became cheap and easy to get and much more powerful.They are able to ignite a pack of matches and shine blinding light miles into the sky."You have this searing intensity, this bright light shining into the aircraft, so you experience flash blindness," said Captain Hamilton, a commercial pilot.Captain Robert Hamilton knows first-hand the power and the danger of lasers."What goes through your mind is, 'Will I be able to complete the flight?'" Hamilton said.FAA Data show about 4,000 laser strikes reported by pilots every year for past five years nationwide.Our research of government records has found numerous accounts of pilots reporting blurred vision, temporary blindness even retinal damage due to lasers.One passenger made clear what he thought about anyone thinking it's all a harmless game."Idiots on the ground who want to play with toys hopefully someone will find them and lock them up," said John Andersen, of West Haven, Connecticut.Newark had 28 reported laser-pointing incidents last year.
– Authorities appear no closer to figuring out the source of those mysterious lasers dazzling pilots over New Jersey and New York even as more incidents are recorded. After pilots reported lasers hitting at least 11 planes last week, nine more flights have been affected, including four last night. Two of the flights were a few miles west of Warwick, NY, one was 20 miles south of Newark Liberty International, and one was 20 miles southwest of LaGuardia, reports WABC. All were under 7,500 feet. Fox News reports laser incidents have been popping up at "a record pace" this year with almost 2,000 as of May 15.
