French CNES satellite control station at Bretigny, France, inadvertently transmitted destruct command to balloons being tracked by Eole satellite (launched Aug. 16), causing 70 of 135 flying balloons to be cut down. Although error was not expected to degrade planned scientific accomplishments of mission significantly, it would delay beginning of scientific experiment by 7 to 10 days, CNES instituted new training procedures to Eole control station personnel on transmitting commands to satellite and designed system which would alarm when certain critical commands-such as balloon destruct, gravity gradient retraction, and activation of magnetic hysteris rods-were to be placed into Eole.
