Heißer Sand (1971)

Captain Jeff Barlow is a pilot with heart and soul. On behalf of a French company, he dares to conduct an experiment that is not without danger: dry ice is to be shot into clouds over the Sahara to make them rain down. The aim is to put an end to the water shortage. However, the artificial rain project is anything but harmless. But Captain Barlow is far too passionate an aviator to be deterred by the danger. And so what has to happen, happens. A sandstorm is Barlow's undoing and he crashes his plane. Lost in the vastness of the Sahara, there is no trace of him. A search operation is launched but is unsuccessful. A race against time begins for Barlow, as his water supplies are running low...
