Aerial sequences were accomplished, often in bad weather to demonstrate conditions under which the airlift was flown, using a Fairchild C-82 Packet as a camera platform, taking advantage of its removable rear fuselage to take panoramic shots of up to 170 degrees. Seaton reported that he finally overcame political complications with Soviet authorities to complete location shooting inside the Brandenburg Gate, which was in the Soviet zone, but that on the day of the shooting the Soviets set up loudspeakers to harass the set with propaganda. The scene was shot without sound and dialogue was later added by dubbing.
