2. When we “arm” the doors on your aircraft, each flight attendant checks the work of his colleague at the opposite door. You’ve heard it a million times: “arm doors and cross check.” Did you hear “crotch check?” It wasn’t your imagination. We get silly sometimes. And yes, despite all the cross checking—maybe because we’re checking crotches instead—once in a great while we screw up and we forget to arm the doors, which means the emergency slides won’t automatically deploy if needed in an emergency. We can get fired for that.
