FBI Investigating Laser Beams Pointed at Aircraft
sakshale writes "In an earlier discussion about Laser Pistols, many people argued about the concept of using them to target pilots of airliners. Apparently the FBI is investigating incidents in Cleveland and Colorado Springs. They issued a warning on December 14th."
How can a laser beam travel round the nose of a plane overhead, and accurately reach the pilot's eyes from say, a few thousand feet away?
The guy pointing it must have steady hands, and damn good vision.
It does have the ring of "post-Sep-11th-paranoia" about it, doesn't it?

This may or may not be a threat. Some interesting thoughts here
But it seems to be that it would be awful hard for something from the ground to actually hit the inside of the cockpit unless it had some sort of tracking device to track the plane, and was high enough to hit the inside of the cockpit instead of the nose cone (perhaps on a tall building or mountain near an airport).
I think this could be another tactic to strike fear into the populace.
Unfortunately, that's the idea.

was a substantial risk andSeastead this.
no it is not.
any laser that the general public can get their hands on will DO NO DAMAGE to a pilot or even distract them.
first off even the high power green ones, at the 100 meters or MORE distance these people are at, they need to retrofit the laser with a tripod, fluid head and a high power scope just to hit the plane.
Now let's addin the fac tt hat the angle if incidence of the beam to the cockpit window is at such an extreme angle that less than 20% of the beam will pass through the window, and THAT will get attenuated further by the cockpit glass.
let's further add that the pilot is looking at the centerline of the runway and not directly at things that might be interesting, and if it's a clear sunny day a reflection glint off cars in the parking lot is 200 times brighter than any consumer laser.
this is nothing but a bunch of people freaking out about isolated incidents.
if I was able to get my hands on a targeting laser, Yes, that MIGHT be able to hit the cockpit window because of the gyro stablization of the optics and laser, but then it's infrared so NOBODY would know it was hitting it!
can I get my hands on industrial lasers? yeah if I look hard enough, but you certianly will not run them off some portable battery for longer than a few seconds.
it is NOT a serious problem. Quit being a scared soccer mom.
Do not look at laser with remaining good eye.
Why does everybody think this is just a case of some kid who bought a handheld laser pointer and is trying to point it at an airplane that flew overhead?
Come on people, it doesn't take a whole lot of imagination to figure out that a combination of a commercial/scientific laser along with a good quality sighting scope mounted on a high quality tripod wouldn't be too difficult or expensive to slap together. Hell, just get a good laser and mount it on top of a good pair of military observation binoculars and you'd probably be ready to rock & roll.
It also doesn't take a whole lot of imagination to realize that from a mountain top or other high peak of land you could target aircraft flying directly towards your position from a few miles away. If it's flying in your direction then its horizontal and lateral positions won't change very much so you wouldn't need a sophisticated tracking system. You wouldn't even need a very high position if you intend on targeting aircraft that are landing - just an open area a mile or so from the end of the runway.
