Codex! What are some cool memories you've been thinking about lately? Think of a specific time or event you've been reminded of, and share it with us. I'll start it out!
Circa 2013 when I was just a young Airman First Class [A1C]. My supervisor/mentor was teaching me how to configure the engine propellers on a C-130 for hydraulic fluid servicing -- look at all those gauges and levers, and lack of facial hair (puke)!
(I'm sure there's another topic out there like this, but oh well)
