The C-130 at the end of the film has a tail number of 4X-FBB. This is the number of a C-130H flown by the Israeli Air Force. -FBB is former USAF 71-1375, delivered to IAF in October or November of 1971. The aircraft has also used tail numbers 4X-JUB and 4X-EBB while with Israel Aircraft Industries (IAI). The Lockheen C-130 Hercules is known in Hebrew as the 'Karnaf', which means Rhinoceros.
The Boeing 707 featured in the film was an early production model, ordered by Cubana (which never took ownership) but delivered new as a 707-139 to Western Airlines on May 13th, 1960. It was then sold in 1964 to Pan Am, which operated it for several years before leasing it to several other carriers, including: Aer Lingus, British Cal., El Al, and many others. It was the 108th 707 off the line, with serial number 17903. In 1979, British Caledonian leased it when the DC-10s were grounded after the AA 191 accident. Its last service was in 1986 to Aerocar Aviation, whose livery appears on the aircraft in the film. It was eventually scrapped in Marana, after more than 30 years of service with more than a dozen airlines, mostly in the Middle East.
The movie was originally to be produced with the cooperation of Delta Force's real-life founder and original commanding officer, Col. Charles Beckwith. The producers wanted to tell the story of Operation Eagle Claw, the failed attempt to rescue the American hostages from Iran in 1979, but they wanted to change the story so that Delta Force completed their mission successfully. Colonel Beckwith left the project in disgust.
