Specific Flight Files, organized chronologically by mission, contain a variety of reports, reviews, photographs and small subject files regarding flights from Gemini III to the Space Shuttle. Files of missions flown previous to Apollo 11 generally contain less material than more contemporary flights. Of special interest are materials documenting the development of the Space Shuttle, and GML's Apollo 8 "Special Notes" describing the decisions and timetable behind the circumlunar flight. Additional materials relating to specific flights are included in NASA Notes and Notebooks, Tours and Trips, and Collected Materials. A number of GML's subject files have also been retained by the NASA History Office in Washington, DC. (see Appendix E).
