1931 ‘CITY OF CAIRO’ KOEPANG, TIMOR. The ‘City of Cairo’ left Croydon on April 4 on a flight to Australia. On April 19 1931 the De Havilland DH66 Hercules ran out of fuel due to strong headwinds and an oil leak while approaching Koepang, Timor. All three engines stopped and the captain attempted an emergency landing 10 miles short of the airfield. On touching down in a field the aircraft hit rocks and lost its’ landing gear. While both crew were unhurt, the aircraft was damaged beyond repair. The well known aviator Kingsford-Smith flew in and collected the mail a few days later. On arrival in Australia it received a backstamp, otherwise no official ‘crash’ markings were put on. This cover has a MELBOURNE 29 AP 1931 arrival cancel.
