Im Himmel ist doch Jahrmarkt(1969)

Five young, pretty female athletes are training for an international skydiving contest. From heaven they basically fall straight into the arms of five charming young men. Their coach is less than thrilled about the flirtation and urges his athletes to concentrate on the contest. He is convinced that love-making will put the victory to risk and asks them for sexual abstinence. The power of love turns out to be stronger, however, and soon the first love couples find each other.
