Air filming was done in the first weeks of September 1976, culminating in a series of air drops of a total of 1,000 men. Supplies were dropped from a number of
Dakota aircraft. The Dakotas were gathered by the film company Joseph E. Levine Presents Incorporated. All aircraft were required to be CAA (
Civil Aviation Authority) or FAA (
Federal Aviation Administration) registered and licensed to carry passengers. An original deal for the purchase of 10 fell through when two airframes were rejected as passenger configured without the necessary jump doors. Eleven Dakotas were procured. Two ex-
Portuguese Air Force, 6153 and 6171 (N9984Q and N9983Q), and two from
Air Djibouti, operating from
Djibouti in
French Somaliland, F-OCKU and F-OCKX (N9985Q and N9986Q) were purchased by
Joseph E. Levine. Three
Danish Air Force K-685, K-687, and K-688, and four
Finnish Air Force C-47s, DO-4, DO-7, DO-10 and DO-12, were loaned for the duration of the parachute filming. Aircraft 6171 doubled as the camera ship on most formations, with a camouflaged
Piper Aztec, G-AWDI. A camera was mounted in the astrodome, one on the port upper mainplane surface, with a third camera on the outside of the forward port cabin window and a fourth under the aircraft centre section. In addition, centre escape hatches were removed to make additional camera ports available, provided that no troops were aboard during filming. A second Aztec, G-ASND, was a backup camera ship on some shots, but it was not camouflaged. An
Alouette, G-BDWN, was also employed. After a mishap with G-AWDI, two locally hired
Cessna 172s, PH-GVP and PH-ADF, were also used. Ten
Horsa glider replicas were built, but a windstorm damaged almost all of them. Seven or eight were hastily repaired for the shoot. The replica gliders were tail-heavy and required a support post under the rear fuselage, with camera angles carefully chosen to avoid revealing this. Dakota 6153 was fitted with tow gear and
Horsa replicas were towed at high speed, though none went airborne. A two-seat
Blaník sailplane, provided by a member of the
London Gliding Club,
Dunstable, was towed aloft for the interior takeoff shots. on 18 May 1976. German vehicles are crossing the bridge. Four
Harvards portrayed American and German fighters. Their original identities were PH-KLU, PH-BKT, B-64 and B-118, the former two aircraft loaned by the
Royal Netherlands Air Force. These were flown by members of the
Gilze Rijen Aero Club, which also provided an
Auster III, PH-NGK, which depicted an Auster V, RT607, in wartime camouflage.
Spitfire Mk. IX, MH434, depicting a photo reconnaissance variant, coded AC-S, was lent by the Hon. Patrick Lindsay, and was flown by aerobatic champion
Neil Williams. Sufficient American tanks, jeeps, and trucks of World War II vintage were found because many of the vehicles were being discarded from European military (almost entirely reserve) units, especially from
Greece and
Turkey. The scenes set around the Arnhem bridge were shot in
Deventer, where a similar bridge over the
IJssel was still available. Although a replica of the original road bridge in Arnhem existed, by the mid-1970s modern urban development surrounded it, making it impossible to use as a setting for a 1940s city. A few scenes were shot in
Zutphen, where the old municipality house and the main church can be seen. Additional scenes were filmed at
Twickenham Studios. The
Motion Picture Association of America initially gave the film an
R rating for its use of the word "
fuck" and depictions of war violence, but United Artists lobbied it to change it to a PG rating so that younger audiences could see the film. Cuts were also made to the film when released in the United Kingdom to avoid an AA rating from the
British Board of Film Censors. ==Finance==
