Other mistake: An Army friend of Ben's uses Ponderosa land to test his hot-air balloon. There are very few clouds in the sky. A balloon in flight is shown but it is obviously stock footage. The sky is filled with clouds and the film contains several black spots and scratches.
Other mistake: A windstorm in the opening scene was obviously created by a wind machine. The branches of the trees in front of the Ponderosa are swaying, but no dust or leaves are blowing on the ground, and the trees in the background are motionless.
