Well, I was taught, if accidently in an F-100 spin.
Look at watch, note time for accident board
Place and hold right hand on PITOT HT switch to ensure accurate IAS readings if out of spin
Place and hold left hand on TRIM FOR T/O button to ensure...ta da...trim for T/O
Wait and watch altimeter for 15,000 feet, if still spinning-EJECT.
IOW, do nothing to prevent the plane from recovering itself.
