The Flying Nun is an American sitcom which starred Sally Field as Sister Bertrille. The series originally ran on ABC from September 7, 1967, to September 18, 1970.
Sister Bertrille could be relied upon to solve any problem that came her way by her ability to catch a passing breeze and fly. This was attributed to her small stature and heavily starched cornette (the headpiece for her habit. Her flying talents caused as many problems as they solved. She explains her ability to fly by stating, "When lift plus thrust is greater than load plus drag, anything can fly." The reason behind that statement was that Sister Bertrille weighed only 90 lbs., and in one episode tries to gain weight so she could stay grounded, but the attempt failed.
