This report is a summary of the status, completed in December 1966, of the Apollo lunar landing program prior to the tragic deaths of Astronauts Grissom, White, and Chaffee preparing for the first manned Apollo flight. This tragic accident will undoubtedly affect to some extent both the schedule and cost of the Apollo program. However, it does not alter the basic conclusions contained in this report, nor the analysis provided.

The structure of Apollo - The Lost and Forgotten Missions follows the development and in flight testing of the Apollo lunar spacecraft prior to Apollo 11 as well as missions planned following that first landing. Drawing upon combinations of archival documentation from the first four manned Apollo missions and future mission plans evolved in the summer of 1969 Apollo - The Lost and Forgotten Missions will fill this void. The text explains how the machines and the men were prepared for the landing on the moon and what would have followed the initial landings.
