A shortage of unsymmetrical dimethylhydrazine (UDMH) rocket fuel was being strictly managed to prevent delays in military and NASA launches. The fuel was produced from raw materials found to have an agent that could cause cancer in humans. Methods had been devised to produce the fuel by removing humans from the step endangering health, but adequate supplies could not be produced before the end of the year. Stopgap measures taken by the Air Force, including strict control and allocation of existing supplies, was preventing the shortage from interfering with any critical launches.
