Not that it's great for the WHOLE gift, but as a partial gift if he doesn't have it yet, Sporty's ornament this year is a glass etching of the Wright Flyer. It's pretty cool and I bet any pilot would want it.
My dad's GPS works in the air (he used it the whole flight from CO to AK and said he wanted to make sure the pilot didn't get lost :roll

- maybe you can give him some of the money for it, but not all.
