The planes here vary from commercial to military. The large airliner in the bottom left was mainly used for civilians as was the top left. These planes where either rented out or privately owned. The other four planes you see where military airplanes. The army planes in the 50s and the Cold War continued over from the previous War. All though seeing slight variations in the form of new weapons, the planes all followed a basic template.
One thing that continues to crop up in my research and thus the pictures is that white star. Its the symbol of the American army, so it got plastered onto anything related to it. In terms of our Movie/Trailer, we have to ensure the star is visible. This can cause an instant recognition of the time and the place.
