A story currently unfolding on a maillist that I subscribe to isreason to review preparations for winter flying. It seems that a group of people headedout on a flight a few days ago and has not reported in. They disappeared from radarsomewhere in the Sierras. It has been cold up there and the chances of survival, for theill prepared after a crash, are slim.
