Dan had wanted to fly but was unwilling to sign on for three years and instead was conscripted. He trained in radar and was assigned to Ground Control Approach and was posted to the RAF base in Gatow, Berlin, adjacent to the Soviet zone. His unit was located at the beginning of the airstrip, guiding in British Avro Yorks and Tudors and the US C47 Skymaster. The aircraft were arriving every two to three minutes and the sky was busy with other western Allied aircraft landing at other airfields in Berlin. When on call his unit lived in a caravan beside the runway, where they were able to sleep, despite the aircraft noise

The Russians were generally regarded with suspicion by the British and with fear by the Germans. He felt that the Airlift was a good thing and that it was appreciated by the German people, who were being fed by it. In addition to food the planes brought in fuel and household goods. For relaxation he enjoyed the local yacht club, run by friendly Russians, and occasionally to the centre of Berlin which was still badly damaged. Here they would sometimes go to the American Mess hall as the food was better than the British NAAFI.

The work was exhausting but he only realised how tiring when he went home on leave and slept for 24 hours! He was on this posting for nine of the eleven months of the Airlift and left Berlin shortly before it ended.
