If you click on Apollo 13 Transcripts, there is an Apollo 13 Technical Air-to-Ground Transcript, which is “the raw transcript provided by NASA to the press during the mission.”
I have noticed some obvious errors, e.g., at 03:00:37:39 it reads “the Sun… will septend an arc of one-half degree”. Makes me wonder if some of the many, many figures were transcribed incorrectly. Also, there are dots and asterisks where the audio was garbled or clipped.
It’s been a while, so: is there a better transcript available? Is there a digital copy of the raw tapes available (which could be cleaned up somewhat with some modern processing)?
I am not in a hurry to re-enact the mission, but this kind of stuff may be of historical interest.
ETA: Oh, it’s a spelling mistake we’re talking about? “septend” vs “subtend”? I see. The logs at the link above (and below) have it spelled correctly.
What’s the obvious error? That’s exactly what he says. “Aquarius, uh, Houston, uh. Freddo, on that uh, to pass that check, the sun is at uhh will subtend an arc of one-half degree uh in the AOT”
It’s a spelling error, and obviously the Sun does subtend an arc of one-half degree. However, if that NASA transcript was not proofread as far as spelling, how can I trust that where it says 33499 it was not really 33449 or 34499, is what I am getting at. The logs you linked to, which do not contain that particular spelling error so might have been independently transcribed, where do they originally come from?
I found Jim Lovell saying, see e.g. here, that the transcription released to the press was garbled. So it would be a mistake to rely on that particular document for anything.
What it is to the OP is that he’s curious. Which is what it is to most OPs of most threads in FQ. This is verging very close to threadshitting. Stop it.
