Airplanes and airshows

Last weekend was the big airplane Fly-In in Oshgosh Wisconsin that Grandma and grandpa and most of mommy's sisters go to each year. They all camp out under grandpa's airplane. Kaelyn was thinking about them all and decided to read the Air and Space magazine that grandpa sends us. She wanted to clarify - "do they really fly upside down?" She thinks she'd be interested in trying that someday!
