Used on Apollo 12 to get back from the Moon

Flown Apollo 12 Command Module instrument panel data card, dated October 20, 1969.

It lists details of the Service Propulsion System (SPS) burn, and the procedures for a surge tank leak and other eventualities. Signed on the back by Richard Gordon stating that the card was “utilized by me on the Apollo 12 mission.” 3½ x 6 inches. 3 patches of Velcro on verso to hold it on the panel.

Interesting that they used a mix of Celsius and Fahrenheit.
