The Stewardesses

In the 1969 Softcore 3-D film "The Stewardesses," a crew of Los Angeles-based trans-Pacific stewardesses take the phrase 'party girls' to new heights as they indulge in drugs and multiple sexual encounters on a single eventful night. Produced on a budget of just over $100,000, the film defied expectations, grossing over $27 million - an astonishing figure that solidified its place as the most profitable 3-D film ever released at the time.
