Goofs

When Howard Walters lands after bailing out of the airplane, blood is visible on his right leg as he attempts to stand. He later wakes up in the prospector's cabin with a splint on his leg. Blood, as the result of a fracture, would indicate a compound fracture of the leg. This kind of fracture can only be resolved with what's called an open reduction and internal fixation of the fracture. A splint would be next to useless in this kind of injury. That's because, in this type of fracture, bone protrudes through the skin. Without surgical intervention, a serious infection is almost unavoidable. And, even if a serious infection were somehow avoided, Walters leg would have never healed in such a way as to allow a normal gait afterwards.

When Walters was making his SOS radio call, the engine sound should have been heard. However, with no oil pressure the engine would have seized up; thus, no engine sound.

The remote hunting cabin is wallpapered with newspapers, but a close look shows the newspaper used is The Hollywood CITIZEN-NEWS, an unlikely publication to have handy in the high Sierras.

When Howard Walters radios his mayday distress call, he gives his number as 14536. When he jumps from the plane, the number on the underside of the wing reads 23621. When the plane crashes and flips, just before the explosion, the number on the top of the wing is NC414N.

The fake background behind the Walters as they drive to the airfield is obvious. Mrs. Walters does not follow any of the curves in the road, the transmission is in Park and the Walters' car passes through another car as if it's a ghost.

In the (very unconvincing) effects scene of the plane crash, the model used is a different type of aircraft from the one "Howard Walters" is shown as parachuting from in the flight scenes.

The scenery outside the airplane keeps changing as well as the altitude of the airplane.

Lt. Tragg testifies that Howard Walters spent the winter at the cabin of Zack Davis. But how could Tragg know this? The only people who knew were Davis, whom Tragg admits he cannot find, Walters, who is deceased, and Janice Atkins, who was not then volunteering any information.

Janice Atkins seems genuinely surprised to learn that the missing Andrew Taylor was murdered by Howard Walters. It should have been obvious to her from the start that killing Taylor was necessary to frame him and keep him from denying involvement in the theft of $130,000 from his father's company.
