[Utah-astronomy] Laser info help?

Hi all, a fellow reporter would like to know about the power of lasers to harm pilots' eyes. A Delta pilot apparently suffered damage to his eyes while flying into SLC the evening of Sept. 21. I know that sometimes people following our astronomy hobby use lasers to point out celestial objects at star parties, etc. What we don't know is whether these things are powerful enough to damage the eyes of pilots. This incident happened one day after first-quarter moon so I doubt anything was going on with astronomy at that time. But if you can help with descriptions of how powerful or weak the lasers are, etc., please give Jenifer Dobner a call at the paper at 237-2122. Thanks, Joe
