KORANGA” 1939 KATHERINE RIVER, AUSTRALIA. On 18 January 1939 the Guinea Airways plane “Koranga” hit a tree on take off from Katherine, near Darwin, and crashed into the Katherine River killing all four crew members. This cover to Melbourne from London has had an explanatory label affixed on arrival. Interestingly, even though the address is completely legible, it has been put in an O.H.M.S. ‘ambulance’ envelope, with a DEAD LETTER OFFICE MELBOURNE 24 JA 39 cancel.
