Man, that is an incredible pic you found, Rag!
When you get down to it, you really do not need a vertical stab or a rudder when you are in command of 8 engines! You can use differential thrust to counteract any crosswind component and still bring her home.
One of the things I miss when flying a PC12 is not having differential thrust available to me! It forces me to jam that dang rudder around from time to time.
