When you fly in a Great Lakes icer that is layering an inch a minute of
impact ice on the airframe, I don't care what you are flying, you are
gonna die... Even the jumbo cattle tubes with heated wings don't fly
IN an icing layer of that magnitude, they use their power to climb or
descend through it at 6000 fpm... Take a GA aircraft into known icing
conditions and you are playing russian roulette...
