Well, My fascination with transportation devices has always been practical. It IS a good idea to know how a car engine works. In my divers ed class, we had a test on the engine, and some questions were ones only *I* got right! I didn't always know the answer, but figured it out logically.
And have you ever seen the wings on some large aircraft? If you get nervous, and don't undestand how they work, DON'T LOOK OUTSIDE! Sometimes almost the whole wing moves, with a gaping hole in the center, to change the aerodynamics. It's bad enough when the diminutive flaps are extended, etc... And HEY, I AM glad to know they are finally using MAG LEV for something besides toys!
And HECK, even some jet engines almost seem to come apart, to reverse thrust on landing so they can have shorter runways! Of course, they have air brakes for the same reason. The air brakes just don't work nearly as well.
BESIDES, I used to be almost like warren buffet. I never dealt with things I didn't know about. Following that logic, I could never fly in a plane without understanding it, so I learned about planes a LONG time ago. I think the first plane I flew on was a 747. That thing wa like a HOUSE! I still remember my father showing me this HUGE empty restaurant, and saying that the 747 was larger than that. This was when big meant LUXURY, an before the big inflations, etc... So that 747 was astounding by todays standards. It had a full bar, couches, and I believe a piano. All where on the top deck of course. Until relatively recently, I think the 747 was the only public aircraft to have such an arrangement.
