Who was watching the friendly skies last week? Was there nobody to dispense coffee, tea or milk? Nobody to fluff up pillows or serve that plastic chicken and steak? No. It seemed that every stunning airline hostess in the world—137 of them from 20 airlines—was at Sun Valley, Idaho for Interline Ski-In. It is better known as Stewardess Week and, unofficially, as the Whole Earth Stretch Pants World Championship, a very hip affair. The girls skied. They swam, skated and danced. They sauna-ed. They partied. They were pursued by tanned, white-toothed ski instructors and graying pilots who should know better. But mostly, they paraded around, leaving the air heady with traces of Faberg� and Chanel until the sedate old ski resort may never be the same. There were slaloms for silver cups, but never mind them. What do you want, glamour or a good race? And when it was all over and the girls put their wings back on, there were surprisingly few casualties. Oh, maybe a hundred broken hearts, perhaps a dented psyche or two. But just one little old fracture. The doctor said it was the prettiest leg he has ever set.
