Edition
Scan of “Apollo 11 Technical Air-to-Ground Voice Transcription (GOSS NET 1)”, NASA Manned Spacecraft Center, Houston, July 1969 (626 pages, file AS11_TEC.pdf), in the item Apollo11Audio of the Internet Archive, uploaded in 2010 by the Houston Audio Control Room of the NASA Johnson Space Center (uploader john.l.stoll@nasa.gov). Excerpt: the Introduction (page 2 of the scan) and the whole of tape 66/4 to 66/12 from the first entry after the ignition of the descent engine, 04 06 33 09, to the end of page 317, 04 06 47 20, that is transcript pages 309 (last entry) to 317. The text was taken from the retyped edition of the transcript kept by the Apollo Lunar Surface Journal (https://apollojournals.org/alsj/a11/a11transcript_tec.pdf, 2005) and checked word by word against the page images of the scan, which is followed where they differ; the scan was preferred to the retype in ten places: “Stand by.” (retype “Stand by,”), “real good. ... about on.” (“. . . real good . . . . about on.”), “Our position” (“Our. position”), “Stand by.” (“Stand by.,”), “that alarm.” (no period), “DELTA-H” twice (“DELTA H”), “Roger. We copy” (“Roger, We”), “- - ...” (“--”) and the speaker of 04 06 35 54, which the scan gives on one line as for CC, faintly, where the retype has LMP (EAGLE); the Apollo Lunar Surface Journal also gives these words to the capsule communicator. Parts of the scan are faint; the words and times that cannot be read on it are those of the retype: in 04 06 35 54 “good to us” and the 3 of “3 minutes”, in 04 06 41 51 the 9 of “9 minutes”, and the times 04 06 36 36, 04 06 38 59, 04 06 42 22, 04 06 43 32, 04 06 43 51, 04 06 44 45, 04 06 45 08, 04 06 45 52 and 04 06 46 06, in part. Ellipses, typed “...” on the scan and “. . .” in the retype, are set “...”; the typewriter’s hyphens used as dashes (“- -”) are kept; straight quotes are set as typographic quotes. Running heads (GOSS NET 1, tape and page numbers) are dropped and the heading “Tapes 66/4 to 66/12” is added; the speaker’s station, in parentheses under the speaker on the scan, is set in italic after it. A handwritten note in the margin of page 317, “4:18 pm EDT” with an arrow to 04 06 45 59, is not reproduced. The communicator list of the Introduction is set as a table.
Rights
In the United States, a work of the federal government (17 U.S.C. 105): the transcription was prepared by NASA’s Manned Spacecraft Center for its Apollo Spacecraft Program Office, and the words transcribed are those of NASA astronauts and flight controllers in their official duties. In France, the rule of the shorter term (article L. 123-12 of the Code de la propriété intellectuelle, after article 7(8) of the Berne Convention): for a work whose country of origin is outside the European Union and whose author is not a national of a member state, the protection lasts as long as in the country of origin, which grants none.
