Garden-variety laser pointers aren't the same as the newer
high-powered green lasers, though, are they? (For example:
http://www.greenlaserbeam.com/ )

No, they are not. They are still not the most collimated beams
around, but they are collimated enough to cover just about the area of
a person's face at a few thousand feet.

The total energy delivered to the eye in this case would be in the
range of microwatts at several thousand feet, and it would be
virtually impossible to accurately aim a handheld pointer at this
range. So it would be more of a nuisance to vision than a damage
hazard.

Unfortunately, there are still more powerful lasers available. Most
people dramatically underestimate the hazards of laser light. I'd be
nervous about those green pointers just out of concern for my own
vision. All you have to do is accidentally aim it at a reflective
surface, and next thing you know you have a retinal burn



You;re an idiot and as usual, are missing the point altogether.

C'mon let's have a reality check. Can you identify a single case of
actual vision damage at significant range from a laser pointer?

Yes. The FAA has documented them, and the Civil Aerospace Medical
Institute has been collecting documentation on laser illumination
events and eye injuries for over a decade.

Even if all the light were collected by the eye and the eye were
focused to maximise energy delivery on the retina the energy of a
laser pointer is just too low to cause damage before the blink reflex
protects the eye.

Not true. That would produce immediate eye damage. Ninety-five
milliwatts concentrated by a factor of 100,000 by an eye lens focused
on infinity will practically punch a hole through the retina even at
very short exposures. Even five milliwatts is dangerous.

That's why they can be sold in stores... think about it!

I have.

No, you haven't/ You've jerked off to it, just like you do with everything
other problem outside getting your single extension cord to take all of
your electrical devices.

And it's a serious problem.

Not if you sit in your room all day jerking off..

Complete ********. Just buy a laser pointer and measure the spot size
after 50'. It's already cm wide.

Laser pointers are hardly the state of the art.


Fjukkwit, nobody said they were.

Eye damage would be so unlikely at 1000' from a laser pointer that I
doubt the veracity of this tale.

Hand-held laser pointers are not the problem. More powerful lasers
are used that can easily damage the eye. And the power of a laser
doesn't diminish taht much with distance, since the beam is tightly
collimated.





Which is the opposite of what you said elsewhere..


Fjukkwit.

It seems that they would have to have at least a telescopic sight on
the laser and have that mounted on a rifle stock, so they could get a
precision aiming.

It would have to be precise to within an inch or so, or the beam would
have to be relatively intense and spread slightly to make a larger
target at a distance. A good-quality laser beam doesn't diverge very
quickly, which makes it hard to hit a small target but greatly
increases the damage if you succeed.



You're an idiot.

The area is an extremely noise sensitive area of mostly antique and

Read into that what you'd like.

The implication is that some people in the area are selfish enough to
think that blindness and/or death are appropriate punishments for
anyone who dares to disturb their desire for silence.



a complete idiot.

Guys...

I swapped private emails with Marco, 'cause I'm VERY familiar with the
area where it happened. As in the "riding my bicycle" familiar.

I hope you are able to help Marco find the responsible person. Even if it was
just a teenage "rich kid" who did it as a prank, and he ends up getting just
a slap on the wrist, it should be publicized so as to point out just how
serious the damage and consequences of such pranks can be.

Then again, if all he gets is a slap on the wrist, and it is publicized, the
result may be that we will see more, not fewer, instances of this sort of
thing...

Fry the *******!!!!

I reacted this way because it irked me that this was not an accidental
event. I'd be kicking myself for days if I did nothing. I'm glad you would
reconsider. If the guy actually got caught, just think of how satisfying
it
would be.

Then their high-priced lawyers should be very happy when the FBI gives them
a knock on their door.

Reading into it from every possible angle, I fail to see how shining a laser
into an aircraft is even remotely justified.

Noise Nazis are a completely different breed. The anti-Santa Monica
crowd used to operate a bulletin board but discontinued it after pilots
started posting there, too. Some of the NNs applauded when somebody had
a crash.

Palo Alto at one time advised a 30 deg right turn after takeoff on 30,
due to East Palo Alto residents taking potshots at airplanes. East PA is
(was) a "low-income" black community with the usual drug and violence
problems.

Those people, like "jgrove', "Bill MulCahy" and "skylune" are, simply
put, nuts and are capable of anything to punish those of us who fly.

The area isn't THAT rich, just sensitive, mostly small, 200 year-old
homes. Some are fantastic, some are dumps.
