that is ...when you land .... safely in an airport. However, when you have emergency-landed in the everglades, its another matter altogether.

I think one can argue that a PSK is NOT needed at all inside a plane. A press of a button and you get what you need. A PSK is needed only when you find yourself in an unwelcoming environment and unfavorable conditions.

However, a PSK has to be in your pocket even inside a plane. So that if you crash land somewhere and you survive the crash, youd have something to help you. It should be assumed that some search party will be looking for the crashed plane. So, food and water are not that really critical. OK, water is critical in case they dont find you the first day, but not food. .

How about a signal mirror or something that might work as a signal mirror ?? I guess that in such a case, I would wish that I was a woman, cuz a small mirror is always there in the purse <img src="/images/graemlins/grin.gif" alt="" /> and no cutom guy will ever raise an eybrow about it. <img src="/images/graemlins/grin.gif" alt="" />
