 Director William A. Wellman adds another to his long line of salutes-to-aviation films in this bio of an aviation pioneer, John Montgomery (Glenn Ford.) In 1883 he built a practical glider despite the opposition of his friends, who thought he was crazy, and of his family, who were afraid that his dreams of flying would hurt his father s political ambitions. He pursues his education at Santa Clara University where the Jesuits lend a helping and understanding hand. An earthquake destroys what appears to be a working model for an airplane, but a gold-sorting machine Montgomery invented, and then neglected, promises to provide for his financial needs to keep working on his aircraft until he gets involved in costly lawsuits defending his invention.
