Walking onto your F-100 at 5am in BNA, finding an avionics box sitting on the counter in the F/C galley, rubbing your eyes and turning to see a mechanic's butt sticking out of the cockpit.
Me: "Um, so, is it bad that this nice shiny black box with lots of pretty wires sticking out of it is sitting here in the galley instead of being there in that panel where it belongs?"
Mechanic belonging to said butt sticking out of the cockpit: "yup"
Me: "So it's gonna be a while"
Mechanic: "yup"
Me: "Ooooookay"
Agent that had suddenly appeared behind me: "So can we board?"
Mechanic: "I wouldn't recommend it"
That was a fun morning.
Thankfully the old crew lounge was still there from when AA had a crew base in BNA. So we found some nice cozy recliners to snuggle up in. Kind of eerie though, a nice, big airy crew lounge, and barely a person in sight....... ghost-town-ish.
