@ricci genuinely surprised these guys don’t make one; would you settle for the pumpkin spice chemtrail controls?

@dan @ricci well since you mention it… I also made these stickers 🙃

the switch & the stickers (& a life-size standee of Margaret Hamilton & a DSKY) were for a display on the Apollo Guidance Computer that I put together for a recent vintage computer fair here in Canberra 💁‍♀️

@itgrrl @ricci also, this reminds me of a story I recently learned about and had been meaning to post about. Did you know that Margaret Hamilton used to bring her daughter to the lab when she was working nights and weekends, and let her play with the AGC simulator?

Her daughter crashed the simulator by accidentally invoking program 01 and resetting the guidance system to believe it was back on the launch pad.

Hamilton felt that was a pretty serious bug but was told "no, there's no way a trained astronaut would accidentally do that."

A trained astronaut did, in fact, do precisely that while Apollo 8 was on the way back from the moon.

She was allowed to fix it for Apollo 9.

@dan @itgrrl @ricci Oh boy, I get to cite the Apollo Flight Journal, complete annotated radio transcripts of every Apollo mission.

A sleep-deprived Jim Lovell was performing a navigation measurement of Alpheratz, star 01 in the computer. But he omitted part of the command sequence and instead entered program P01, a prelaunch initialization program.

The astronauts and mission control spent much of the next three hours recovering from that.

106:27:22 Lovell: Houston, Apollo 8.
106:27:24 Collins: Apollo 8, Houston. Go ahead.
106:27:28 Lovell: Roger. For some reason, we suddenly got a Program 01 and a 'No Attitude' light on our computer.
106:27:35 Collins: We confirm that.
[…]
106:30:04 Collins: Okay. Jim, while we're working on this procedure, we'd like to know did you select 01, did you get a Verb 37 Enter. 01 Enter? [Pause.]
106:30:15 Lovell: Let's see, I'm not too sure, Mike. I might have done that, yeah.
