Tyvm, Anon. Sorry if it may be a slide as the Pike closed in 1979.
SOME RANDOM THOUGHTS on countdowns and clocks: When does the clock run out? In football, it tuns out at the end of each quarter and end of the game. Endgame. The clock runs out at the end of a countdown. Q's NASA countdown drop? Forty years ago the shuttle Columbia STS-1 launched. A clock kind of runs out when an alarm is set. When does the first alarm ring? The NASA article mentioned the launch being delayed (Scrubbed like a computer) due to a computer software problem. Like Dominion/Smartmatic? The problem was resolved and the shuttle was launched- 12APR1981, the date today being ON THE FORTY-year anniversary.
PS- I posted the NASA COUNTDOWN post thingy on General and the baker found it notable.
