dod.gov link is incorrect, though.

I learned from FBI.gov that shining a laser pointer at a plane is a federal crime. The more you
know i suppose.

There's real reasons for that. At 40,000 feet, a laser beam isn't focused and it's more like a
spotlight to the pilots. You can blind them and potentially cause a crash, killing hundreds of
people.
Most planes have a sensor on them that can pinpoint the location that the laser is coming from,
so it's very likely you'll get caught if you try this.

Wouldnt it be really hard to hit a plane considering they are going sanic speed and that it takes
time for the laser to travel that far?

Crusing speed of a 777: mach 0.83 (282.4407 m/s)
Cruising speed of light: mach 880,975.3233 (299,792,458 m/s)
The speed of a plane moving doesn't really counter-act the speed of light.

Im talking about human error, it seems like it would be pretty hard to keep on a target the size
of an eraser head that is constantly moving faster than the speed of sound. I'll admit that I
assumed that laser beams behaved differently than light though. More of a chemistry man, really.

I didn't say that, i just remembered shining a laser through a prism and writing a paper on how
it behaved differently than white light. I never said I was smart. I just assumed that even at
light speed there would be enough error at that distance to be off enough to miss the plane.

Ever watch a plane fly overhead. Doesnt seem to be moving very fast does it. Should be quite easy
to track due to the relative distances and the fact the light source will effectively immediately
come in contact with the aircraft. Use your noggin anon.

A laser is different from regular light, but only that it's CONCENTRATED light. The word "laser"
is an acronym, which stands for:
Light
Amplification by
Stimulated
Emission of
Radiation

It's not really an issue when the plane is cruising at altitude. The other anon is correct that
the laser isn't perfectly collimated (no laser is; law of physics)
But the real issue is primarily when the plane is landing. The laser light reflects off the
window of the plane and it turns the entire cockpit a bright green or blue or red or whatever
colour, and the light can still be strong enough to overload the pilot's eyes - like flicking on
and staring at a flashlight in a dark room - you can't see anything.
Since people were being complete morons about it and not controlling themselves, the government
has mandated that lasers above a certain power range require extra paperwork and made it illegal
for people to shine lasers at aircraft.
