FBI offers $10,000 bounty for arrest of laser-wielding idiots While laser pointers are very useful for presentations and distracting cats, the FBI is fed up with idiots using them to try to blind airline pilots, and is offering $10,000 to anyone who provides information leading to an arrest.

Raise the stakes, lift the 60-day limit - and people will start building drones with an IR cam to track the suspect from laser beam detection until reaching proximity, and a regular flash-equipped cam to take the the bastards' picture. And these would obviously fly below 200', and well clear of runway extended centerline.
"...and people will start building drones with an IR cam to track the suspect from laser beam detection until reaching proximity..."
Just wondering, what happens when you shine a laser pointer at a drone? Anything much? Because if you will be flying them at people armed with laser pointers, you should probably make sure they can cope.

If you're lucky it goes out of control and flies into the dumb pricks face and blinds him/her... instant "punishment fitting crime". In fact maybe someone should write the code to make it possible and open source it.
it doesn't have to be redesigned, they just need an old one. 20 years ago, my girlfriend's unit had a pilot drop on the GLD instead of the target...a month of her unit being confined to quarters ended with a determination of pilot error.
"there are sunglasses, there can be windows that reflect laser beams"
Not likely. The 20% transmission ratio of laboratory laser eyewear would probably have disastrous effects on a cockpit crew who must read instruments while flying at night.... The optical quality of such systems also becomes a factor because slight amounts of distortion or haze which may be of no concern in the laboratory may be a major concern to pilots flying at low altitudes and high speed. Also, there may be a variety of laser wavelengths/colors that may need to be defended against. If all wavelengths are protected, the goggles essentially are opaque.
windows, not sunglasses.. there are loads of different type of glass for windows which block UV rays, and skyscraper glass which wont smash with a plane impact..
adding some kind of gel to the window for cockpits can no doubt relect or remove the glare from a direct laser beam
then replace the glass in all cockpits with laser beam proof glass
"gel it what makes windows double glazing and strong, gel is inside all double and triple glazed windows"
Yes, the 'gel' between the panes of glass in a double glazed window is normally a very light substance consisting of a mix of around 79% Nitrogen and 20% oxygen. I hear that the aerospace industry is familiar with that substance and indeed relies on it utterly already. There is probably a thick layer of it protecting the cockpit glass, and it doesn't seem to help.
i originally said it would be more convienient and cheaper in the long run to just make laser beam proof glass with some new kind of gel
americans are always crying about planes and lasers when no other country cares, they will bring in the national gaurd and raid festivals which have lasers on stage and tell everyone to go home because american pilots are sissies
I know there are ancient goggles that may be that bad, but for less than $500 you can buy multi-band goggles with good optics and 75% transmission. Laser lines are very narrow and good filter design can remove essentially all commercially available laser wavelengths without much visible issues. I have long wondered why not more pilots wear those.

Cue a rush of none-too-brights egging their more pliant mates into practising their laser marksmanship at the local airport ("it'll be a larf innit"), then shopping them for the reward, failing to get their ducks correctly in a convincing row before picking up the phone, and ending up doing a bit of bird themselves. Judging by my local rag, there'd be a plentiful supply if they tried it in the UK.
Perhaps the inclusion of a mandatory mercury switch that would cut out the power when tipped more than 30 or so degrees about level would solve a large percentage of abuse? The people doing this brain dead activity probably couldn't figure out how to defect such a simple cheap device. People who had a legitimate above horizontal need/use could buy a more restricted or registered version
I've looked into laser pointers and it's been no more blinding than looking into a desk lamp. Plus, how many miles away from an airliner do you have to be to have line into the cockpit^h^h^h^h^h^h^h flight deck? From that distance you can blind a pilot? When I point one of these things at a PowerPoint screen from 5 metres away the little dot is all over the place - how does anyone keep it on the aeroplane windscreen long enough to cause anything other than a millisecond's flash?
"to date 35 pilots have required medical treatment after being hit" WHAAAAAT? Those weren't laser pointers, they were weapons-grade, mains-powered, floor-mounted and with a sighting system. I call bullshit on this...
I'm not for one second advocating going out and giving it a whirl, but I do believe that pilots that get their knickers all in a knot over laser pointer "incidents" are being just the teensiest bit over-dramatic.
You're quite mistaken. Battery-powered lasers the size of a small flashlight are readily available for a few hundred dollars that put out 1W and even 2W -- that's 2000mW, probably about 1000 times the power of the laser pointer you looked into. I've read that shining one onto a wall and looking at the spot for a few seconds can cause permanent retina damage.
I agree that they're weapons-grade, but floor-mounted and mains-powered? Absolutely not. And why do you need a sighting system when you can see the beam clearly?
I don't understand either how they manage to hit such a small target so far away (it obviously wouldn't work from straight below), when normally you can't even see the beam (or even if you could - which would by the way mean so could anyone else, following it straight down to you). I can't imagine randomly waving it in a plane's general direction would register a hit long enough to matter in any possible way. So what gives?
@ DropBear
You've actually touched on one of my biggest complaints with science-fiction movies where lasers/rayguns are used -- You DON'T need sights for a projected-energy weapon. Sights on a firearm evolved because the things tend to be heavy and cumbersome and have a tendency to wobble, and (on rifles, particularly) to help the shooter adjust for wind deflection or projectile-drop at distance, neither of which should be much of a problem with an energy beam.
The easiest way to point a laser-pointer with good precision is to tape it to an outstretched index finger. With a larger/heavier one you may need to tape it to finger, hand and arm. Either way, pointing with arm extended at the object you want to hit should do for most purposes. If I wanted to hit and hold on a moving object, that's how I'D do it, at least.
If you MUST have a "gun-shaped" hand-weapon in your movie for dramatic and/or recognition purposes, you design it such that the index finger lies in a groove parallel to the beam-emitter, with the other three fingers wrapped around the grip and, possibly, a thumb-stub as the firing button.
Point-and-shoot -- We've all been doing it since childhood; no sights required.
I watched a program on this once and, if memory serves, the beam diffuses by the time it reaches the aircraft i.e. it's not like trying to aim a dot through a windscreen, it's like trying to light it up with a torch.
From inside, the whole cabin was lit up (and you can see the beginnings of this in the article photo) - it means the pilots can't see out and wrecks their night vision. Obviously the power in some of the lasers is pretty high if 30-odd pilots have needed hospital treatment.
Applying economic forces to this problem might have some success, but does this sound a bit desperate to anyone else? If this program principally communicates that it's almost impossible to catch people who do this, then it could backfire.
I also have to wonder who does this (11 x day)? If these are terrorists, then I have to say that I'm thrilled at their ineffectiveness, but I wonder how many arrests will result. It's not like terrorists go to the pub after a hard day's jihad and complain to the bartender.
At a guess I'd say that most of these people are morons and even if they got a bunch of moron convictions, I don't know how many morons that will dissuade because... they're morons. I'll bet their money would be better spent exchanging laser pointers for $10 McDonald's coupons.
"I'll bet their money would be better spent exchanging laser pointers for $10 McDonald's coupons."
Great, so they'll buy a cheap laser pointer for a buck or two and swap it for a coupon that's worth five times the value and then buy another pointer...
I just looked up a 40 watt system:
https://www.youtube.com/watch?v=XsNsM4HDx-c
The one I was thinking about from a previous search a few months ago was about the size of a very large hand torch. And far more powerful.
It wouldn't take much ingenuity to rig one of these things up in a van or a car boot, firing it through a hole or a car lamp. Since that is what a some snipers are or were already doing in Iraq and Afghanistan, just using ordinary rifles, I wonder why there are only 11 a day being used successfully. And only on aircraft.
