The radar system allows the aircraft to fly at low altitudes and therefore reach the drop zone undetected. 雷达系统允许飞机在较低高度飞行，然后到达未被发现的空投地区。
The pilots were supposed to drop supplies to the snow-bound villages,but the organization was poor and they pranged up the whole operation. 飞行员应该往被大雪封住的村子空投物品，但由于组织工作没有做好，他们的空投没有成功。
