All this talk about idiots shining lasers in pilots eyes has me
wondering if we shouldn't add a laser pointer to the collection of
knives, blankets, and food? Anyone think one of these would work as
a signaling device?


Answer is "Yes, probably work very well" -- esp. if you get one of the
green ones, though they're substantially more costly than the red ones
($150 vs $15).

Post your query to sci.optics or rec.skiing.backcountry and you'll
probably get more detailed answers.

I would add that if you do get a pointer, green is the most visible,
and keep it to a legal 5mW pointer. Pointers are limited to 5mW
for a reason - it's *extremely* unlikely to cause any eye damage.
