Ha! This strip really resonated with me (though I never forgot what Chuck did here). I've taught ground school for several years on and off, and it took me a while to get used to the idea that there were things students would ask which I would not have an immediate answer for. At first I felt awful and embarassed, then I learned it was a fact of life for anyone. What finally drove that point home was an encounter with a Thunderbird pilot. At an after-hours unwinding party after an airshow a couple of years ago (I worked our local airshow for many years) I chatted up a Thunderbird pilot, hoping to get some interesting tidbits on flying the F-16 that I could use in teaching ground school the following week. I asked him what Vy was on the F-16. His response: "I don't even know what that is." Well, heck, I thought... if he doesn't know that, I guess it's okay if I don't know or forget things on occasion.
Then there's almost always one jerk in every class whose mission is to humiliate you in front of everyone else. One dufus had designed model airplanes for many many years and knew more about aeroydynamics than I ever could or would. He got his jollies out of asking things that I had no clue about and then explaining his question, and the answer that he already knew, to the rest of the (bored) class. Finally I told him that there was absolutely no need to go into his level of detail in order to get a private pilot's license. But, still, once a class, he would have to humiliate me. If I was able to answer his question, he'd keep asking more until he found one I didn't know the answer to, then he'd shut up, his mission accomplished. The rest of the class didn't like him, either.
I mentioned him to the instructor who was actually flying with him (I wasn't a CFI at the time), and the CFI just laughed. "Yeah, he tries to land the airplane like it's a model, too, no matter what I tell him. Until he admits I'm right and starts doing things properly, he's never going to solo."
The dufus quit both lessons and ground school not too much later.
