Laser Strikes On Aircraft Increasing In Frequency (usatoday.com)

puddingebola writes: The FAA is reporting a record number of laser strikes on aircraft for 2015. From the article: "The Federal Aviation Administration recorded 5,352 laser strikes through Oct. 16, up from 2,837 for all of 2010. ... Some airports have reported more than 100 laser strikes this year: Los Angeles had 197; Phoenix had 183; Houston had 151; Las Vegas had 132, and Dallas-Fort Worth had 115. On July 15, during a 90-minute period, 11 airliners and one military aircraft reported laser strikes near New York City-area airports. Those incidents remain under investigation by the FAA, FBI and New Jersey state police."

The hardest part, though, is keeping the laser pointed at the target. It's essentially impossible. People have tested this repeatedly - it's on YouTube. The bottom line is that a handheld laser can only ever manage to very briefly flash the cockpit of a flying aircraft, and the beam intensity at such a range is non-dangerous even if the laser is quite powerful. It may be surprising to a pilot and could cause a brief but dangerous distraction, but the hype of blindness (even temporary vision loss) is grossly exaggerated.

But now they are so cheap that people can buy them as if they were toys. What do you think the chances are that some parent will buy a laser pointer for a child (or maybe someone will just carelessly leave it out) -- then the child (thinking it is a toy anyway) will shine it in his eyes just to see what happens. Heck I would be really surprised if this hasn't happened already.

    On a side note I would imagine that if the plane were at a very high altitude then it would not be as easy as you may think to shine a laser pointer on any part of the plane (let alone into the cockpit window.) Then again if the plane is at a high altitude then a beam from a common laser pointer will likely expand enough to no longer be that dangerous. I guess this is only a when the plane is very close to the ground almost immediately after a take-off or right before a landing.

Red laser pointers virtually all comply with this. Green pointers are hit-or-miss, since the cheap DPSS laser inside has highly variable power output depending on unpredictable factors. In my experience measuring the power output of green pointers (and I've measured a lot of 'em), they are generally 3-5mW but sometimes you get a hot one that pushes 5-10mW. They can all be cranked up with tinkering though, sometimes to 100mW or more! It's the tweaked green pointers and black-market IIIb and IV devices that cause some concern. 5mW in the eyeball is extremely unpleasant, but does not cause retinal damage - especially with the poor beam quality (and thus large focal spot size) of handheld lasers. A tweaked-out DPSS pointer running tens of milliwatts can definitely cause instant permanent damage at short range though, and the 500mW to 1.5W blue diodes are quite dangerous (but totally awesome).

      Here's the thing, though: None of these lasers are really dangerous at long range. The beam quality is universally terrible, which results in high divergence and therefore large beam diameter at long range. The total amount of light produced by even the most powerful handheld lasers is not very much, and quickly loses its brilliance when spread over a circle a few meters in diameter. At one mile, a 2mrad beam will be approximately 10 feet in diameter. A 1W laser would then have an intensity of 0.138W/m^2, or 0.0138mW/cm^2. That's nothing.

Private or commercial, nobody should be regulating away everyone elses enjoyment of the stars to maximize their enjoyment being part of a tiny minority who gets to look down on the world. These things aren't even really visible except at night and they are flying with instrumentation then. Commercial pilots aren't even actually flying the plane except during takeoff and landing, frequently they are napping in that cockpit.

    As for the rich thing.

    They are rich and therefore people who are trying to use a federal agency to prevent the people who worked for the wealth they are enjoying from enjoying what is left and free, the stars. I have no sympathy. It is not punishing the rich to support putting them on the same level as everyone who is not rich. It is not punishing the rich to reach the immediate conclusion that any benefit they get to enjoy should be denied immediately if it infringes on everyone who is not rich. There are million times more people in the 99.999% by wealth than the top 0.001% by wealth and since there are million times more of them their interests are a million times more important which makes the least of the common mans interest more valuable than the most important of the top 0.001% percents interests should they conflict.

    For example there is a million times more merit to proposing free national mayo clinic level healthcare for everyone but the top 0.001% funded entirely by a tax on the 0.001% than in recognizing their right to property. Especially when the reality is that they no more have a right to property than we have a right to good health the only actual right is the right to take what you can and protect what you can and there are a lot more us ants than there are you grasshoppers.

    In that case I sincerely apologize for the snarky tone but instead hope my snarky response was at least informative. In short, the light on a plane is tiny and low power relative to sheer enormity and light output of a star the difference is vast even from so far away and there are so many they fill the entire sky where the plane is in just one place and easily hidden by cloud cover.

    You can see the pointer because even though the sky might seem clear to us it is still filled with particles of dirt and moisture that highlight the beam. Actually you might even have seen this with high powered lights that aren't lasers when a car dealership has an event or there is a fair/circus or the like. Sometime those lights are powerful enough to see a beam that projects a fair distance up. On some nights you just see it reflect off the clouds but other nights you can actually see a beam project into the air.

    Also often a night seems clear but there is still plenty of wispy cloud cover which will highlight where a beam is pointing.

    I lived about 10 blocks West of the Sears tower and used to take a cheap laser pointer to the park with me when I walked my dog, because she likes to chase it around (yeah, I heard it wasn't really safe, but the dog is 16 years old and she doesn't seem concerned about the possible dangers).

    I can see the pointer on the side of buildings blocks away, but I can't see any beam. Is that because those cheap laser pointers don't have the power of the fancy emerald ones? If I blow smoke in front of the laser pointer, I can see a beam for a second, but not otherwise unless it's foggy.

    Thanks for the informative response. Now I'm gonna have to go get an expensive laser and point it around. If I get in trouble, I'll tell them you said it was OK.

    I've been lasered when flying my plane. The beam is big at these long distances, so ti isn't a tiny beam going into your eye, it lights up the cockpit and looks like a very bright point of light. Since your eye focuses the light to a point, lasers can be dangerous at fairly low power levels.

    In a plane even if the beam is not damaging it is very distracting, and distraction is a major cause of aircraft accidents. in my case they kept the beam on the plane for many seconds so it was clearly intentional.

    Its pretty common - several pilots I've spoken to have been lasered. This is the second time its happened to me.

    Sounds like there's money to be made by an enterprising individual that creates a coating that blocks key frequencies or at least scatters them reasonably well without obstructing the wind screen's optics too much. Being that this is dealing with avionics, I'd imagine the testing and licensing would take years though. Do you think pilots would find any value in that at some reasonable (relatively speaking - owning a plane or boat is like hooking your wallet up to a vacuum) price?

    One thing I never see published is the details about the flights. Certainly if the pilot is near an airport, especially during landing and takeoff, then obviously the perps are engaging in malicious behavior.

    However, my math says that the major airports reported in the article received 778 of the 5,352 reported incidents in 2015. I live in a residential area that is quite some distance from any airport. A substantial number of aircraft violate the 1000 foot above ground level FAA minimum for residential neighborhoods. I have tried, many times, to call someone, somewhere, who might give a shit about this very annoying violation and there isn't anyone who will do anything (including just returning a phone call), short of my hiring a PI and a lawyer.

    Most disturbing is the helicopters flying what I estimate to be within 200 feet of my house. Although it is a very sturdily built house, the whole thing shakes when the helicopters pass by. Also incredibly annoying is the dip-shit in his WWII fighter plane practicing his tricks, and sometimes just diving and climbing endlessly.

    If I were a lesser person, since I cannot appeal to any authority that will take any action, whatsoever, I might choose to take a more violent approach than just thinking of them as total assholes.

    Only slightly less assholes are the clueless journos who report the stories. Usually it comes from the establishment wannabes at Ars Technica, where critical thinking flies out the window, though this time it's USA Today, and the story is always the same: Report the huge number of incidents, then mention the slim minority that occur right next to an airport. It sure would be nice to see someone actually analyze this data to give people a better understanding of what might be driving this behavior, as I wouldn't be surprised if just asking pilots to follow the law might result in some unsubstantial quantity of these incidents going away. Of course the real problem with this is that it reveal that pilots are also aggressors, so it isn't in that industry's interests to pursue such ends.

    Don't look at sun with remaining good eye. And sunlight isn't coherent light, so the comparison is skewed from the start. I recommend that you try looking into an eye-safe laser beam from a few hundred yards away (so the energy of the beam is spread over a spot two to three feet in diameter). The experience will not be dangerous, but nevertheless quite unpleasant, and this little experiment should cure the misconception that looking into a laser from afar couldn't be a problem.

    Obviously the lack of temporal coherence in sunlight is irrelevant here. Spatial coherence does have some influence on how bright the source appears. Sunlight is fairly spatially coherent at about 4.7mrad divergence on Earth. That's comparable to a bad laser pointer, and not too much worse than a good one. Coherence is much less important to this issue than M^2 value or other measures of beam "quality" that correlate to focal spot size. The sun wins on those metrics. I've stared into many laser beams of different powers and wavelengths, sometimes intentionally, occasionally accidentally. I've been on the receiving end of high power beams from long distances just to see what it's like. A 150mW 532nm beam of about 1.5mrad (a decent quality DPSS module) is pretty darn bright from 3/4 mile away at night, but it's definitely not dangerous. Try it.

    It would be like making the cockpit glass out the same stuff they make laser safety goggles out of. The thing is, you can't easily filter out just one wavelength of light, so the safety goggles for green lasers are orange tinted, and the red laser glasses are all green tinted. I'm guessing most pilots don't want orange or green windows on their plane. And if you wanted to filter both the red and green wavelengths you might as well just paint over the windows.

    Maybe if they actually build those planes where the pilots don't have windows, they can have some mechanism that drops the appropriate filter in front of the camera when the plane gets hit with the laser.
