Apollo 13 Moments of Interest / Re: 033:56:11 Recovery team bartering. Beer vs. Pineapples

« Last post by bfeist on November 21, 2023, 04:29:16 pm »

I found this particular gem because it's just one minute past a much more important historical artifact: confirmation that the IRIG-B time signal encoded on the MOCR tapes is lock-step with the clocks used by the human controllers and support crew. Just a minute before this barter there is an exchange between Houston Recover and Pacific Recovery where Houston clearly counts down the GMT and GET clocks so that Pacific Recovery can adjust their ship clocks to match.

In the attached annotated spectrogram, the speaker speaks the phrase "eight, nine, MARK, 50 seconds". Below each utterance are the time code markers output by the IRIG-B decoder software that we wrote for Apollo In Real Time. The "MARK" phrase lines up perfectly with the GET timestamp "33:53:50" / GMT timestamp "1970-04-14T05:06:50".

I love this so much. For those of you unaware, @ke6jjj is the person who wrote the algorithm that we used to restore the mission control audio back to mission time.

Recovery Houston (id unknown) offers Recovery Pacific (id unknown, but likely on a ship in the Pacific) a trade of a six pack of "Cold Pearl" for two pineapples on return. Haggling ensues.

To further emphasize the human quality of what these ironclad-willed flight controllers do on a daily basis, you want to know what EECOM John Aaron was doing at the exact same time that RECOVERY was making a trade for pineapples?

Looking for a trash can.

This is an absolute gem of a find. Thanks for locating this. It really truly drives home how history was made 53 years ago, and how we sometimes take for granted that what we're listening to is just the digital facsimile of the media of that era.

A sad day indeed. We need to get Apollo 8 done in real time.

And now Frank Borman. One of the most accomplished astronauts, including CDR of Apollo 8, has passed away at the age of 95.

Fred Haise laughing about Ken trying to come up with procedures to allow the crew to shoot pictures of the Service Module when they separate.

Of course there's this now famous phone call between Marilyn Lovell and Ken where she's trying to get an understanding of the situation after the onboard explosion.
