@mcnees Benjamin Snavely (now deceased) was the one who told me about it. You used to be able to see the spare mirror at the Air & Space museum. The Kodak group were a tad annoyed it wasn't their's going up.

@mcnees I knew one of the engineers at Kodak whose group built the backup mirror. He's still smug that their mirror didn't have this problem (I still don't understand how it was missed in the prep work, as it's not like they couldn't swap it out).

@mcnees it may still be issuing stamps but service has gotten a lot worse since they were privatized. Parcels now take four months when they used to take a week, and letters are variable. I still haven't received a letter from my parents and they posted it from the UK a month ago.
