Terminator 3: Rise of the Machines (2003)
John Connor and the rest of the cast must go to the sky to attempt and maintain one step ahead of the robots while racing for their lives and trying to stop them from taking control. I am not sure what could have led to this minor detailing in the movie that we surely have missed while watching it
As you can see in the shot, when they come close to the plane on the ground, they can obviously see the call number N3035C. Once in the air, the planes’ IDs become N3413F instead. Because of the limitations of filming and renting planes, especially while in the air, the explanation for this is most plausible.
