At the beginning of this episode, the bell rings on Joe Louis sparring and the corner man removes his mouth piece as Joe heads for the stool. The next shot shows him with his mouth piece still inserted and then the corner man removes the mouth piece again while he is sitting on the stool.
While in the first time jump, Bogg has no boxing gloves on his hands despite having them on before and after.
When sparring with Joe Louis, Bogg isn't wearing any protective headgear.
When Jeffrey takes over flying the plane and the skies were supposedly cleared of all other air traffic, we see a shot with a plane flying off the right wing.
The pilot who coaches Jeffrey to land the plane is in a control tower. As the camera zooms in, we see "San Francisco International" on the side of the building. When Jeffrey lands the plane in Salt Lake City, however, the coach greets him there in person.
When the outside of the Salt Lake City airport control tower is seen, clearly marked on the building is "San Francisco".
