However I remember reading about Pappy Boyington (Baa Baa Black Sheep VMF-214 fame) flying Corsairs in the pacific, and getting the A/C so finely trimmed and using rigged up rubber bands and string on the joystick so that it nearly flew like it was on an autopilot, so a pilot could catch a nap on long flights. And if the sleeping pilot started to drift off course his wingman would give him a wake up call over the radio.
