As the two nurses and their dates are driving to the party in a truck, there is an obvious cut in the rear-screen projection behind them.

At 0:28:00 Robert Montgomery is on a motorcycle and comes upon a flock of geese, then in slowing down unintentionally runs over one of them.

Set during World War I (1914 - 1918), at about 30 minutes into the movie, there is a scene where Robert Montgomery lands his plane and approaches some fellow pilots who are talking nearby. As they talk, contemporary 1920s vehicles can be seen passing on a distant road (at the upper left of the screen, over Robert Montgomery's shoulder).

Women's costumes and hairstyles are those of 1930, not World War I.
