アポロ・ソユーズテスト計画
If Apollo 15 had flown as an H mission, it would have been with CSM-111 and LM-9. That CSM was used by the Apollo–Soyuz Test Project in 1975, but the lunar module went unused and is now at the Kennedy Space Center Visitor Complex. "Endeavour" is on display at the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Dayton, Ohio.
