NEVER aim laser pointers at aircraft!

You should NEVER aim a laser pointer at or near an airplane or helicopter. It is not safe, you may be arrested, and you may help get laser pointers banned. Below is more information about these three aspects.



Aiming lasers at aircraft is not safe


The beam CAN hit an aircraft

If you aim a laser beam into the sky, it may seem to end, as shown in this unretouched photo:



However, this is a visual illusion, as detailed here. The beam actually continues even if the light is no longer scattered back to your eyes. Some people have been arrested because they thought the beam could not reach an aircraft -- but it definitely can! From the air, the beam can look like this:



Even a very weak beam can be a distraction. The photo below shows a 1 milliwatt beam seen at a distance of 20 kilometers (12 miles) across Tokyo.

Obviously, seeing laser beams and flashes is distracting to pilots. This is one reason you should never aim at or near an aircraft. (Also, notice that the green beam two photos above points right back down to the laser’s location. This makes it easy for a police helicopter to direct ground officers for an arrest, as described later on this page.)

Distracting or flashblinding pilots is dangerous

Another problem is that the beam is much larger at long distances than you might think. Even though the laser projects a small, millimeter-sized dot close up, at longer distances the beam can be many inches across. When the beam hits the windscreen of a cockpit, or the bubble of a helicopter, imperfections in and on the glass spread the light out even more:

The light often is spread so much that the pilot cannot avoid it:



Laser light in the pilot’s eyes causes glare (inability to see past the light). At higher power levels, it can also cause temporary flashblindness and afterimages (like when you look at a bright camera flash, and cannot see for a many seconds afterwards). Since the beam can’t be held completely steady on the cockpit, pilots experience one or more of these bright flashes:


Glare -- the pilot cannot see past the light as long as the laser is on the cockpit windscreen.


Flashblindness and afterimage -- the pilot cannot see until the afterimage has faded. More photos from this FAA test are here and here.


To make things even worse, a pilot being targeted may also be worried about eye damage and eye injuries, and the possibility of the laser being an aiming device on a weapon. A worried pilot is a distracted pilot -- not a good thing during critical flight phases such as landings, takeoffs and emergency maneuvers.

For all these reasons -- and especially due to the distraction, glare and flashblindness effects -- you should NEVER point a laser towards an aircraft. (It is not even smart to aim directly at stars, since a slow-moving far-away aircraft could look like a star. Instead, if you are pointing out stars at night to others, circle the star as described on the Tips for outdoor use page.)



You may be arrested or worse


You may be arrested

Laser users are frequently arrested for aiming at airplanes or helicopters. It is surprisingly easy to find you. And as authorities take laser incidents more seriously, they are putting more effort into finding perpetrators:


1: Police helicopter is targeted by laser pointer on the ground. 2: Helicopter crew use Laser Event Recorder to locate pointer via GPS, and record its wavelength. 3: GPS details enable helicopter’s thermal (infrared) camera to find suspect, and send police patrol on the ground to arrest the person.

You may go to trial

This is expensive and a major hassle. You do NOT want to hire a lawyer to represent you in a trial with a state or federal prosecutor.

You may go to jail

In October 2008, a California man was sentenced to two years in prison for aiming a 3 milliwatt laser pointer at an aircraft. Note that he was using a relatively low-powered laser, about the same strength as a supermarket checkout-stand laser scanner. In January 2009, a Cleveland Ohio man was sentenced to three years in prison for hitting two airplanes and two helicopters. In January 2011, a Massachusetts man received a 3-year prison sentence for aiming at a helicopter.

The aviation-incident news page on this website has many more stories about incidents and arrests, plus we have a special page with a long list of fines and jail sentences for laser misusers.

You may get shot

Because laser gunsights are common, police get very worried when someone points a laser at them. In Florida in 2005, a man was killed when he refused to stop pointing lasers at officers. A similar situation happened in Thailand in 2010. You don’t want to cause any misunderstanding where officers in a targeted police helicopter “shoot first and ask questions later”.

There have even been cases where ordinary citizens get upset with laser pointer harassment and kill people, such as in Greece in 2011 and in Russia in 2013.



You may help get laser pointers banned


Laser pointers may be banned

In 2012, laser-aircraft incidents happened more than nine times each night in the U.S. You can understand that pilots and the FAA are upset about this. If laser pointers were banned in the U.S., this would be fine with them. Some U.S. cities, such as Ocean City MD, Ocean City NJ, and Myrtle Beach SC have severely restricted or banned laser pointer sales and possession. New Jersey’s legislature passed a bill to ban laser pointer sales above 1 mW; the bill was vetoed by the Governor. New Zealand in 2013 restricted laser pointer sales above 1 mW. Countries such as Canada and the U.K. also are considering bans on laser pointer sales.

So if you like using laser pointers, don’t add to the long lists of aviation and non-aviation laser incidents.

Laser pointers have already been banned in an Australian state

New South Wales officials got fed up after lasers hit airplanes landing at Sydney’s airport, in March 2008. The Australian state banned laser pointers and put them in the same “dangerous weapon” category as guns and crossbows. Possession and/or misuse of laser pointers can get you a fine or even up to 14 years in prison.



How to stay safe and keep pointers legal


NEVER aim a laser beam at an aircraft, a vehicle, or towards strangers. In other words, DON’T ANNOY PEOPLE WITH THE LASER BEAM.
