The ancients wrote that the great things to be seen are sun, stars, water and clouds. I think they forgot the round engine.
I have a fair amount of experience flying jets and as much fun as I had, I do have to agree - there is absolutely no mystery to a jet engine. The air travels through it in a straight line and doesn't pick up any of the pungent fragrance of engine oil, hydraulic fluid or pilot sweat.
The rules for the operation of a jet are basic. When I first had some beginning airmen to teach there was this preprinted poster with the "four forces of flight". Lift. Weight. Thrust. Drag. Each were represented by a drawing of a man. Someone, of course, drew a dress on Mr. Drag, which now would just get them sent to the corner for "sensitivity training". But it wasn't all that much harder to teach airmen gas turbine engine technology. I have kitchen equipment more complicated.
Go on! Go read it! You know you want to howl with laughter, especially if you've ever tried to perfect angling the clipboard so it deflects the oil spume from the DeHavilland Beaver's engine when you're adding more oil in flight!
