Sky Giant

Richard Dix plays 'Stag' Cahill, an ex-military commercial pilot who is coerced into serving as the assistant to uber-disciplinarian Colonel Stockton (Harry Carey), who is charged with turning the Trans-World Air Line School of Aeronautics into the best darned pilot school in the world. Colonel Stockton's son Ken enlists in the school, and he and Cahill engage in an escalating game of pranks to vie for alpha dog position.  Ken is played by Chester Morris, who was the special prosecutor in my last movie, Smashing the Rackets.

The action of the movie culminates in a plane crash in the arctic wilderness, from which Ken and Stag must hike for days through the mountains before reaching safety.

The real meat of this movie is that both Stag and Ken love Meg, played by Joan Fontaine. Meg marries one but loves the other. It all gets straightened out in the end.

Joan Fontaine and her sister Olivia de Havilland are still alive.
