Mig21SM,
Nice photo. I'm sorry I don't have that detail but one of the posters on this forum was a Navigator at Wildenrath at the same time and has written a book about his experiences on the Phantom during the Cold War. The Pilot and Navigator normally flew as a constituted crew so his hours would be near enough for comparison.
