movie where there was a flying plane in a desert

A cargo aircraft crashes in a sandstorm in the Sahara with less than a dozen men on board. One of the passengers is an airplane designer who comes up with the idea of ripping off the undamaged wing and using it as the basis for a replacement aircraft they need to build before their food and water run out.

When an oil rig in the Gobi Desert of Mongolia proves unproductive, an aircraft crew are sent to shut the operation down and fly them out. On the flight out over the desert on the way to Beijing, Capt. Frank Towns and co-pilot A.J. are unable to keep their cargo plane, a C-119 Flying Boxcar, in the air when a violent sandstorm strikes. Crash-landing in a remote uncharted part of the desert, the two pilots and their passengers -- a crew of oil workers and a drifter -- must work together to survive by rebuilding the aircraft. Soon, low supplies and a band of merciless smugglers add even greater urgency to their task.
