Two WSO's in my class finished #1 & #2. #1, Roger Locher, had 3 Mig kills as a WSO. Couple classes after me DeBellevue, the WSO MIG Ace after washing out of UPT initially, came back to UPT and ended up flying fighters.
After flying LL missions with any extra fuel I usually gave the stick to the WSO. On a 10 hr deployment from TX to Germany my WSO flew at least a quarter of the flight.
