Wings

 

According to Wikipedia:

  "The film, completed with a budget of $2 million, was the first film to win the Academy Award for Best Picture (then called "Best Picture, Production") for the film year 1927/1928, and won a second Academy Award for Engineering Effects. Primary scout aircraft flown in the film were Thomas-Morse MB3s and Curtiss PW-8s.

    For many years, Wings was considered a lost film until a print was found in the Cinémathèque Française film archive in Paris and quickly copied from nitrate film to safety film stock.  It was again shown in theaters, including some theaters where the film was accompanied by Wurlitzer pipe organs."
