Tom Dahl

I am a professional software developer with a life-long interest in the space program. I fondly recall watching the Apollo 11 lunar landing live as a ten-year-old boy, and collecting newspaper articles about Gemini and Apollo missions. I've continued to follow the space program up to the current amazing robotic missions, and have enjoyed sharing with my now-adult children the history and significance of extra-terrestrial exploration.

One of the nicest aerospace museums in the United States is the Museum of Flight, outside Seattle, Washington. I traveled cross-country in order to visit the "Flight Capsule 3" Viking lander, a backup unit that was never completed. Its partially built state exposes its internal structures, making it a boon to study.
