Mr. P was Bun's gunner, but P was sick that day, so Snoopy was picked up out of the fantasy draft and he became Bun's gunner for that day.
The real feat was that the Sopwith Camel was a single seat plane so Snoopy had one hand on a tether to the plane and the other firing the machine gun...
Now that was noteworthy!
