This challenge idea came to me. Maybe it\'s boring, but I thought I would mention it anyway. Use Kerbal to fly the Mercury and Gemini flights. Follow the orbit-inclinations and approximate altitudes of each flight (should be available somewhere). For the Gemini\'s that rendezvoused with spent Agena or other rockets, those would have to be launched first. At least one Gemini changed the plane of its\' orbit, and one boosted up to about 800 miles. Gemini 6 and 7 rendezvoused with each other. Then splashdown in a specific ocean. The rockets should look kind-of like the real ones, with the correct number of stages, etc. And do it all without killing any kerbal-nauts. A trip into real history, eh? (or too boring?)
