Hi All,
One problem the Moon Walkers had to overcome, and is not well known, was the circuit breaker incident on Eagle.
After landing, one of the astonauts broke the toggle or button off the circuit breaker.

He brushed past it in his rather cumbersome space suit. It had to be the one which was needed to ignite the engines to lift off.
After a little bit of thinking one of them was able to stick his pen into the breaker and manipulate the contacts,

activate the ignition circuits and they were off.
Cheers Marty
