Two of operation 'Freshman's' glider planes crash violently into the Norwegian mountains, their target, Ryujkan. Without Henriksen’s approval, the Germans heighten security to maximum level at Rjukan. Leif Tronstad persuades the Allies to send in a small team of Norwegians to break into the factory and blow it up from the inside. Operation ‘Gunnerside’ is then created with Knut Haukelid in command. In Germany, Heisenberg continues to experiment with the heavy water.
