The Loadmaster

A new US airline flight attendant was in England when she saw a British cargo airline crew at the airport. She noticed one of the crewmembers had two stripes on his sleeve.
“What does that mean?” she asked.

“I’m the loadmaster” the gentleman said with a rich British accent. Not completely understanding the cockney, the flight attendant said
“Gee, back in the US we call them Captain, not Lord and Master.”
