Sumburgh, Shetland Islands

The Flight now has only one operational Whitley, the long-range Z6473, but there is no operational crew to fly it. F/O Hockey is still not fit to fly. Fortunately it is the start of the ‘dark’ period. S/Ldr Knowles orders F/Lt Oettle to return to the mainland and base by boat train.
