Operation Haylift is a 1950 American aviation film by William Berke starring Bill Williams, Ann Rutherford, and Tom Brown. The film - a fictionalized account of a true story - documents the United States Air Force mission in 1948–49 to save thousands of cattle caught in the snowdrifts of a sudden winter storm in northern Nevada. "Operation Haylift" involved scores of cargo aircraft delivering hay to the stranded animals.
