I recently visited the Ronald Reagan Library in Simi Valley, California. Two of the more popular items on display are a former Air Force One jet (you can see the nose of this aircraft in the upper-left corner of this image), and a former Marine One helicopter. This image is one of my favorites taken during my visit. I have always loved helicopters. Their ability to gracefully hover and pivot is simply intriguing to watch. With their long blades and sleek designs, helicopters look every bit as impressive sitting on the ground as they do in flight. While serving in the military, I had the incredible opportunity to spend an entire afternoon repelling from a UH-1 helicopter. Amazing fun!
