In the two parachute scenes the internal and external shots are of two different types of air planes: The external shots are of C-130 Hercules planes and the internal shots are of C-47 planes. Most likely the external shots are stock footage, as the C-130 Hercules did not come into service in the Danish military until 1975 and the planes seem to have American markings on the side. In the internal shots the ground is visible in the background and is clearly not moving.
