Fox: Commercial Pilots 'attacked' with laser
Fox News | Greta Van Susteren

Posted on 09/28/2004 8:12:49 PM PDT by ableChair

Greta Van Susteren reported that a Delta pilot enroute to Salt Lake City was lazed in the cockpit this last Wednesday. Only country I know that has that hardware (for lazing bomber pilots) was the Soviet Union. Pilot reportedly required medical treatment and this was not a minor injury (weak laser) wound. More will come out to tomorrow as this story hits the print press.

Look at the posts. One of your cohorts (which, by the way, I took simultaneously) claimed that clear air was denoted by 1. You just posted that it was 0. Which is it? Get your story straight.

If I dig up the original article, I'll pass it along

Please do. This is scary stuff.

The linked paper on laser attenuation through fog has numbers for alpha for clear air all the way through to fog.

The alpha they cite is in km units.

As I said earlier, this is easily proven by using their formula in reverse. 0.43dB/km for an alpha of 0.1 as they cite requires the units to be km.

My "story" isn't what some other guy posts.

I'm responding to you. Not others.

Zero is no attenuation loss.

Atmospheric numbers are linked here:
http://www.freespaceoptic.com/WhitePapers/Comparison_Of_Beam_in_Fog.pdf

0.1 is an attenuation factor for 1.0km in clear sky.

or, 0.0001 for one meter in clear sky.

I've got an electronic welding helmet that darkness the glass in milliseconds. Would this kind of technology work to avoid this laser problem?

In theory it would. It could be triggered by special circuits designed to detect narrowband light sources. I bet the pilots wouldn't like it.

Sorry but I can't respond as I'm not sure to what the Moderator is objecting.

It probably had something to do with your exceedingly insulting language, you think?

An attenuation factor of 0 is the ideal condition, not 1. Hence it is attenuation
Oh really. Then who posted that 1 was "clear air"?

Clear air is .1, haze is 1.

That would be odd. I read their policy and there's nothing there about it. A poster used the same tact with me before, was reported and nothing was said. So, I assume it's acceptable. Besides, that language started in this thread with a post to me from the guy that later got the Calculus question wrong...what's his handle? If that were the case I would think something would be said to him as well.

I read some sites for commercial Nd lasers. But from what I could determine the optimim range for the high-power models (400 watts or above) was 1-5 meters.

I'm probably misunderstanding most of what I read, being ignorant on the subject. I would like to see some more definitive writings.

I'm getting nostalgic. This is like being back in high school.

Actually, yea! All I need to know are the parameters for debate. If there aren't any I'll play as hard as my opponent.
