Useless trivia Department:
Gemini 6 launched AFTER Gemini 7.
A buddy of mine worked on the Manhattan Project. After the war, he wound up at Monsanto, where he generated a couple of hundred patents. As a token of their appreciation, the firm gave Andy one of the first (pre-production) HP “scientific” calculators, in 1971. Andy let me have it, on open-ended loan! It out-performed my trusty slide rule, and it offered precision beyond two decimal places! The next year, when it went on sale as the HP-35, it cost $395 - the equivalent of $2,550 in 2020 dollars, which buys you five unlocked 128GB Samsung S-10 smart phones.
Glad that the launch went well, even though I’m not much of a fan of manned spaceflight.
