The first stewardesses were actually nurses hired to make passengers feel safer. Women who wanted to be “sky girls” had to meet strict requirements. In addition to being single, they had to be under 25 years of age, under 5-feet-5 and under 116 pounds. Not only did they tend to passengers, they were also expected to haul luggage, fuel the plane and help pilots push the plane into the hanger after flights. "Stewardess" was replaced with the term: "flight attendant" in the 70s.
