As mentioned in an earlier post, the 3rd Class Petty Officer on the Itasca should not have saluted the 2nd Class Petty Officer, but the mistake that is more unusual is that when the Commander steps into the room later on, no one says, "Attention on deck!" The standard call when an officer is present. Coming to attention is done instead of saluting indoors, and is stood until the officer says, "Carry on".
When Amelia Earhart is signing the Lucky Strike endorsement, George Palmer Putnam hands her what appears to be either a ball point pen or a mechanical pencil. Ball point pens were not in common use until the late 1930's. If this were a pencil, one would never sign a contract in pencil.
(at around 1 min) When Amelia Earhart and George Palmer Putnam are about to enter the railroad station, you can clearly see the "no firearms permitted" sign on the entrance door at the extreme right of the frame, just behind the Asian couple exiting the building - obviously not in keeping with the era.
In the scene when the "Friendship" is about to take off for the first time, we hear the sound of an engine firing and running up. At the same time we see the center engine just starting to turn over, and neither of the other two engines are running.
When Amelia Earhart is flying and thinking about riding the horse, the horse and rider switch from trotting to galloping between shots but the sound is of a horse cantering throughout the entire scene.
The black and white film of the Lockheed Electra taking off the first time shows a window next to the door, and a window in the door. When the scene reverts to color, the window in the door is missing.
When Amelia Earhart walks into George Palmer Putnam's room during/after the cocktail party, her necklace is underneath the sheer part of her dress as she walks in and sits down. Later in the scene when the shot cuts from Putnam back to Amelia the necklace is on the outside of her dress rather than underneath as it had been seconds before.
When "Bill" Stultz is near the dock where the "Friendship" plane is getting ready to take off, a coffee cup is in his hand. When he decides to get on the plane, he walks down the dock and puts his cup on a barrel. When the plane turns into the harbor a few seconds later, the cup is gone.
When Amelia is approaching Karachi, it is 1935 and the caption on the screen states "Karachi, Pakistan". Pakistan wasn't formed until Partition from India in 1947. So in 1935 Karachi was still part of India.
The Coast Guard crewmen on the Itasca are wearing their "whites". They were obviously working, so the enlisted men should have been in light blue chambray shirts and denim pants; the officers should have been in khaki.
The third-class petty officer, who is nodding off, salutes the second-class petty officer when he enters the room. Enlisted men only salute officers, not each other. Additionally, Navy and Coast Guard personnel never salute indoors, and they do not salute while "uncovered" (not wearing headgear.)
When Amelia Earhart asks George Palmer Putnam to dance with her, music plays as soon as she turns the radio on. Radios of the era had vacuum tubes, which had to warm up before anything came from the speaker.
