The Apollo 11 collection contains transcripts of communications between Mission Control in Houston, Tex., and the astronauts Neil Armstrong and Buzz Aldrin during the first landing on the moon, July 20, 1969. Divided into two segments, both titled "Apollo 11 Mission Commentary," these transcripts includes a record of transmissions during the landing itself (27p.) and during the first moonwalk (27p.). Both are autographed by Armstrong.
