Super Guppy at sunset

Last Thursday October 4th was the 50th anniversary of the launch of Sputnik back in 1957. I was a speaker at an event that night at the Pima Air & Space Museum in which I talked about Apollo. Before the talks got started, I took this picture of the Sun setting behind the Super Guppy aircraft that is on display at the museum. This airplane had a large cargo area to hold large items like Lunar Modules or rocket stages and could transport them from the factory to the launch center. At the left edge of the image on the horizon is Kitt Peak. This image was taken at 55mm focal length with an exposure of 1/1600 seconds at f/5.6, ISO 400.
