It was many months ago that I promised a build report for one of my friend Alfonso's Space Shuttle (http://www.axmpaperspacescalemodels.com/) Lately, he's been releasing more Shuttle Mission Configurations, and not only the Space Shuttles are there, but the options are: - Space Shuttles (Columbia, Challenger, Discovery, Endeavor, Atlantis, Enterprise and even the mockup Pathfinder). - Stack configuration (External Tank and Solid Rocket Boosters, and a special Rollout configuration) - Open bay Shuttles with payload In total, up to date, you can find 19 Shuttle Missions, all different from one another (minus 2 or 3 almost equal), of them 6 can be build as open bay Shuttles with payloads. If challenge taken, you have work for the next 3 or 4 months. And here is the Endeavor STS-49, maiden flight for the Endeavor Shuttle. Its mission, repair the Intelsat 6 satellite. Here's the base structure with the open bay almost ready to be loaded.
