Respiratory therapist Justin Misuraca was sitting in the co-pilot’s seat of a Flight for Life plane, helping the pilot watch for other air traffic, when a bright green light filled his vision. He closed his eyes and looked away; when he opened his eyes he was blinded for a few seconds.
A few days later he saw an eye specialist. Misuraca said the specialist told him “…there was a burn all the way to the back of my eye, and I’m missing 30 percent of my vision in an upside-down V.” He was told the burn was “half a millimeter from my optic nerve.”
This screenshot from the KUSA 9news segment “Next” shows Justin Misuraca with a triangular blur overlay that the program says represents the visual effect of the laser injury. The area is highlighted below between the green lines to better define the area.
Misuraca reported this in an October 25 2017 interview with a reporter, so the vision loss was still present over a month after the laser illumination.
The pilot on the September 15 flight also reported temporary blindness but has no permanent injury.
According to Flight for Life, there have been “at least a dozen times in the last couple of years” that the organization’s aircraft have been targeted by a laser beam. The source of the September 15 laser illumination is unknown.
From October 25 and October 26 reports by 9news.com
The incident happened around 11 pm on August 8 2017. An off-duty police officer happened to see the pair on a hotel balcony in Torremolinos, a coastal resort town about 13 miles south of the airport.

Pilots of at least three commercial aircraft had complained about being dazzled with green light as they prepared to land.
While the British father and son were not arrested, Spanish National Police called it a “very serious violation” and said the fine could be from €30,000 to €600,000 (USD $35,000 to $600,000).

The incident happened September 30 or October 1, 1987. According to an October 2 1987 Pentagon statement, a U.S. Navy P-3 reconnaissance aircraft was “illuminated by an intense light” from the Soviet ship Chukotka. An Air Force WC-135 intelligence plane also was illuminated.
The statement said the light “disturbed” the vision of the co-pilot, and “although preliminary medical evaluation has shown no apparent damage, further detailed tests may be required to determine if, in fact, no damage to her eyes occurred.”
Sen. Malcolm Wallop (R-Wy) initially disclosed the incident. He said “In my opinion, anything that disturbs your vision for 10 minutes damages your vision. The effect was to temporarily blind that co-pilot."
According to the Pentagon, they believe the light source was a laser. The Pentagon statement did not speculate on the reason for the illumination of the aircraft.
The New York Times referenced one official who said the Soviet ship might have tried to harass or blind the pilots, while a naval consultant said it could be that the laser was used to track missiles and was inadvertently shined at the U.S. aircraft.
Such illumination had occurred before, according to the Pentagon statement.
The 1987 edition of a Pentagon publication, Soviet Military Power, said that "recent Soviet irradiation of Free World manned surveillance aircraft and ships could have caused serious eye damage to observers." The following picture and caption appeared on page 113 in the book:
A group of three U.S. ships — a destroyer, an amphibious assault ship, and a dry cargo ship — were transiting international waters in the Strait of Hormuz, according to a U.S. military statement. The Iranian naval vessel, said by one source to be a missile ship, came within 800 yards of the assault ship and scanned two of the U.S. ships with a spotlight.
The helicopter was flying alongside the deployment when the Iranian targeting laser was aimed at it, setting off the flares.
There was no report of injury to the helicopter pilots. A spokesperson for the U.S. Navy’s Fifth Fleet said “Illuminating helicopters with lasers at night is dangerous as it creates a navigational hazard that can impair vision and can be disorienting to pilots using night vision goggles.”

UPDATED JULY 16 2017 - Iran claimed it did not point a laser at the helicopter. The Tasnim News Agency said “A top commander of Iran’s Navy denied reports that the country’s naval forces had pointed a laser at an airborne US Marine Corps helicopter in the Strait of Hormuz back in June. Commander of Iran's First Naval Zone Admiral Hossein Azad categorically denied reports of such incident.”
The report had no additional details, such as what could have set off the helicopter’s flares as claimed by the initial U.S. report.

The helicopter crew radioed ground officers, who arrested Mark A. Geohagan, 55, of Ocala. He told officers it was “not a laser” but a laser comb. Geohagan said he was testing the distance the light could reach, and that he meant no harm. Geohagan was charged a few hours later with pointing a laser light at a driver or pilot.

The Bosley LaserComb Elite used by Geohagan has nine red 650nm laser diodes arranged in a line, that normally are directed towards a person’s scalp. When aimed into space, it produces a single, “extremely bright” spot of light as described in more detail after the “Read More…” link below.

Case 1: Johnny Alexander Quenga, 28, of Fresno
On March 5 2015, the Fresno Police Department helicopter Air 1 was illuminated by green laser light about six times over ten minutes. One crew member, who had been illuminated by lasers numerous times in the past, suffered temporary flashblindness, afterimages, a headache lasting several hours requiring pain medication, and dizziness. He said the beam was much brighter than in his past experience. The pilot had a momentary loss of night vision, and flew a wide orbit to avoid the beam. The pilot directed ground officers to the location.
However, a patrol car on the way to the suspect’s home was broadsided at an intersection by a Toyota 4Runner. The Jaws of Life were needed to rescue one of the officers. Both officers in the car were treated at a hospital for serious injuries. The officer driving was knocked unconscious, had upper body and leg injuries, and some chipped teeth. The passenger officer had a broken leg and a fracture in his back that may require surgery. (The 4Runner driver and passenger suffered minor injuries.)

When officers finally reached Quenga’s home, they found he was listening to police department radio traffic. He said “he could hear everything the officers were saying and knew they were looking for him and [he] had possibly hidden the laser.” Quenga claimed the laser beam came from a house behind him. He further said he worked as a security guard and knew he could lose his job for misuse of a laser.
The suspect, realizing he had been spotted, took off in his car — with the laser. However, ground officers caught Polson at the entrance to his subdivision and took him to jail, where he was charged with misusing a laser device which is a felony, and for opposing a police officer during an arrest which is a misdemeanor.
According to the Tampa Tribune, in September 2013 Polson sent an email to the newspaper saying he had been harassed for several years by law enforcement helicopters and aircraft. He said the harassment occurred daily but “made no sense” because he is “no threat to anyone.”

The aircraft was on patrol at 2:35 am, at about 1700 to 2000 feet altitude, looking for impaired drivers, when it was illuminated by a laser beam. The pilot was able to use infrared imaging to see Huffman, standing outside of a mobile home. Officers on the ground said Huffman initially denied having a laser pointer, then he suggested the pilots mistook it for a flashlight. He said he was not aware the plane was a State Patrol aircraft.
Huffman lives with his grandparents. His grandfather told Q13 Fox News that Aaron was ““playing with a toy flashlight and that’s exactly what it was — it was a toy flashlight. Just one with, what do you call it, a laser beam? Well, now I can understand it since 9/11, but I’m 60 years old, I can understand it. I think ahead. He’s 20 something years old. He don’t think ahead.”
In the comments section of a News Tribute story about Huffman’s arrest, a commenter named Heather Huffman wrote “He has not done this before the laser wasn’t even $7 to buy had no warning label and he didn’t even know it would reach that far.”

The helicopter crew was investigating an attempted burglary when they were hit “about four or five times” by a person in a car stopped at a traffic light. Parrott was charged with knowingly and willfully pointing a laser lighting device at the pilot of an aircraft, which is a third degree felony in Florida. Federal charges under the February 2012 law -- with a maximum penalty of five years in jail and a $250,000 fine -- may also be filed. In addition, the state attorney’s office was considering charging the driver of the car, Steven Romano, age 55.
During the arrest, Romano’s car at right, has six police vehicles behind it.
This incident comes less than a month after an Orlando-area teen was arrested June 7 for aiming a laser at a Seminole County sheriff’s helicopter (just north of Orlando), and only two days after an Orlando-area teen was arrested June 30 for aiming a laser at an Osceola County sheriff’s helicopter (just south of Orlando).

UPDATED November 18 2014 - Parrott was found guilty of aiming the beam of a laser pointer at an aircraft in the special aircraft jurisdiction of the United States. Parrott faces a maximum penalty of five years in federal prison. His sentencing hearing is scheduled for February 2, 2015. From an FBI press release from the U.S. Attorney’s Office, Middle District of Florida.
Jacob Finch of West Palm Beach, Florida, told TV news stations that he was using a green laser pointer to exercise his dog. He said “I guess the laser got over that fence and shot out.” Finch lives in the path of the airport, and was using the laser at about the same time as the reported incident, around 7 pm on December 9 2013.
Finch indicated he had no idea of the danger and would not do it again: “Oh my gosh, this possibly hurt somebody? I mean we were oblivious.... I feel horrible. It could have hurt somebody. No more lasers.”
As of December 14, there were no news reports indicating any arrests or other progress in the case from the Palm Beach County Sheriff’s Office.

When Ron Tubbs failed to surface from his dive off Kaena Point, Oahu, his dive partner contacted the Honolulu Fire Department. A helicopter was sent to search; first from the Fire Department and later a Coast Guard MH-65 Dolphin helicopter.
As the skies grew dark, Tubbs saw one or both helicopters but they were searching too close to shore. He pulled out a green laser pointer and aimed in the direction of the aircraft. (News stories are not clear as to which helicopter, or perhaps both, Tubbs aimed at.)
Tubbs later said, “When it got dark I think they finally realized they saw the beam of the laser way off in the distance and [I] took care not shine it in their eyes or anything, but in their direction and it reflects off the moisture in the air, so it makes a pretty big beam.”
Ron Tubbs, diver rescued by aiming laser at helicopter to get its attention

The laser worked to get the aircrews’ attention. Tubbs was rescued by the Coast Guard helicopter after about four hours in the water, and was taken to a decompression chamber.
Coast Guard Lt. Chris McAndrew said “With how dark it was last night, it would have been impossible to see him unless we were right on top of him, knew exactly where he was. The way were able to find him so quickly was because he had some kind of signaling device.”
From Hawaii News Now, the Honolulu Star-Advertiser, and the Huffington Post
UPDATED February 11 2014: Ron Tubbs wrote to LaserPointerSafety.com, to give advice for anyone who might use a laser to attract rescuers:
“The green laser saved my life. The failure of my other safety gear put me in a very serious position. My physical condition was failing quickly. I was vomiting when they picked me up from over four miles from the search area. Any delay due to the use of my laser to get help was very serious.
“My life was depending on the Coast Guard and Fire Department rescuers. To hurt those who are saving other people's lives with a by shining a laser at them is very serious and could have cost me my life.
“The Coast Guard pilot who saved my life reported to me that the green laser and/or any LED light is not seen with their night vision goggles. Three of the four crew were wearing those goggles.
“I will never scuba dive without my green laser again and have it as a safety device. Even so because night vision goggles do not see LED light I would suggest a nice expensive strobe and very bright flashlight (not LED) too or flares as the main signal device in addition to the laser. Also the Fire Department helicopter would not go near a laser as they have only have one pilot and a glass helicopter floor.
“To shine a laser towards a helicopter could actually cause the rescue to be delayed. Also shining the laser right into their eyes could blind the ones you need to rescue you so be very careful if you do use one to get help. Do not put those trying to rescue you at risk too. Shining in their direction and not at them will work well enough.
“Thanks to those who saved my life. Please all do not put them at risk further by shining a laser at them! “

During the incident, the pilot put on protective eyewear specifically designed for laser incidents. The tactical flight officer was said to have “extreme anxiety” and was temporarily flashblinded during the incident. Afterwards he had “spotty blindness and a minor headache.” Police said the Class 3 laser was capable of causing permanent blindness and burning skin.
The nature of the glasses is a mystery. Although a Gizmodo headline said the man wore “laser glasses”, the word “laser” was not used in the original CBS DFW story used as Gizmodo’s source.
A photo (above) taken by Barber shows the man wearing two pairs of glasses. A Google Image search for “laser glasses” and “laser pointer glasses” turned up one type of laser-emitting glasses but these have a different design: thick rims with a silver laser embedded above the nose. An eBay search turned up a similar pair; these do not appear to match either of the man’s glasses.
The boy told police that he “had not planned to blind the pilot and had only directed the beam at the flashing lights of the airplane.” Police said his parents would be fined 500 rubles (USD $15) for negligence.
The deputy chief of police at the Barnaul airport, Andrey Spiridonov, said that tragedy was avoided by a miracle.

Coast Guard and Navy personnel boarded the vessel on April 7 but were unable to find any laser device, or evidence of a possible device. U.S. Navy Lt. Cmdr. Jack Daly was then examined by military laser eye injury experts, who found “there was a high probability that the minor burns on the lieutenant's right retina were caused by multiple laser exposures such as might result from a single glimpse at a repetitive pulsed laser.”
The American naval officer took this photo in the Strait of Juan de Fuca showing a red light on the M/V Kapitan Man. The light led some to suspect a laser. However, subsequent inspection did not find a laser, and in the location of the red light were “two deep red running lights … that met the guidelines established for sidelights.”
The U.S. Defense Department concluded that “[a]vailable evidence does not indicate…what the source of such an exposure might have been. Specifically, there is no physical evidence tying the eye injury of the American officer to a laser located on the Russian merchant vessel.”
The Strait of Juan de Fuca laser incident was also discussed in the August 2004 medical journal Archives of Ophthalmology. The article “Assessment of Alleged Retinal Laser Injuries” describes “Case 5” and concludes that “…[n]o evidence of laser injury was found in the years after the incident by 17 other ophthalmologists, including 5 neuro-ophthalmalogists and 8 retina specialists. A trial was held 5 years after the incident in which the retina specialist who made the initial diagnosis steadfastly maintained all the photographer’s [naval officer’s] symptoms were due to retinal laser injury. A jury ruled against the photographer’s claim for damages against the ship’s owner.… The patient had real complaints, but they were caused by preexisting autoimmune problems rather than by laser injury.”

Paresi, 20, faces university judicial board hearings with penalties that could include expulsion. He was also charged by University of Pittsburgh police with two felony counts of “causing or risking a catastrophe.” Finally, an FAA spokesperson said they will pursue civil penalties of up to $11,000 per violation.
On July 17 2011, at midnight and again at 3 am, medical evacuation helicopters reported seeing green beams coming from the University’s “Cathedral of Learning” skyscraper. Police confronted a group of students leaving the building after the second laser incident. Parisi, 20, spoke privately to an officer and said that he was the one who had been using a laser pointer.
Parisi was also found to have a fake Virginia driver’s license. He was additionally charged by the police with carrying a false identification card.

The arrest site is about 5 miles east of Midway Airport:
From the Chicago Tribune. Thanks to Joanna Skubish for bringing this to our attention.
UPDATE, MARCH 19 2011: The aircraft was a Southwest Airlines flight from San Francisco, with 137 passengers and a crew of five, that was landing at Midway. Police arrested Shania Smith, 21, and Elvin Slater, 23. Smith had just met Slater for the first time earlier that day. Smith said “I don’t know how it got in my car”, and that the first time she saw it was during the arrest, according to the Chicago Tribune. Slater’s uncle said He's a good kid. He just didn't know what he was doing.” Both Smith and Slater were charged with “discharging a laser pointer at a police officer and discharging a laser at an aircraft”, which are misdemeanors.
