What I'm reading: Rogue Warrior by Richard Marcinko; One True Love, by Barbara Freethy.
I recently read a book where a character was learning to fly a small jet. The character was already an experienced pilot, but hadn't been trained on this type of aircraft. The author is also a pilot, and as I read the scene—pages and pages of it—it was clear enough to me that the author was simply showing his readers how much he knew about the topic.

To me, it was a hair-pulling couple of chapters. Maybe pilots enjoy it, but to me, it would be like showing a person learning how to drive a car, and following the along as they learned where to put the key, how to turn it, where the brakes were, and then followed along every inch of driveway and road on their first excursion. Had absolutely nothing to do with the story other than getting the character qualified so he could drive the company plane.
The trick to showing details is not to show the reader how much research you've done, but to use only what the POV character needs to show in the scene. If it's a naïve character, then they're likely to be thinking more about the details, either a how-to, or a more detailed description as they absorb new surroundings. But if they're experienced, then they're probably barely going to think about things. How often do you walk into your bedroom and notice the color of paint on the wall, or the precise shade of blue of your bedspread?
