- 1201 Alarms: In the final minutes before landing, several 1201 computer alarms
warned of a computer overload, as too many tasks were left running by mistake.
Unphased, Neil Armstrong switched to manual and landed without the computer.
- In the audio of the last 2 minutes before landing, a ground controller can be heard interrupting
with a terse and cryptic "60 seconds", followed by, 30 seconds later, [wait for it] "30 seconds" -

Armstrong landed and cut the engine 15 seconds later - he had 15 seconds of fuel left!

"bunch of guys about to turn blue."
- During preparations for departure from the moon, Buzz Aldrin accidentally broke a switch
on the main control panel. It turned out to be the ignition switch to the main engine. There
was no leaving the moon without it. Nothing like losing your car keys when you're parked on the moon!
As Houston scrambled for a solution, Aldrin used a felt-tipped pen and successfully flipped the switch.
