I have just got a pre release copy of an interesting book called "Dick Richey - the Flying Fisherman." This is a great read, it covers many searches and a couple of incredible rescues by this guy in a Super Cub, and various other aircraft. The flying abilities and techniques of some of these old timers was pretty exceptional, as was the disregard for some of the bureaucracy of the day. Found the website
Tasmanian Flying Fisherman index, it has info there.
