PREFACE

This preliminary transcript was made from voice tape recordings of the Gemini 7 flight crew debriefing conducted December 19 through December 21, 1965 at the Crew Quarters, Cape Kennedy, Florida.

Although all the material contained in this transcript has been rough edited, the urgent need for the preliminary transcript by mission analysis personnel precluded a final edit prior to its publication.
