1938 ‘CALPURNIA’ LAKE RAMADI, IRAQ. On 27 November 1938 the Imperial Airways S23 flying boat ‘Calpurnia’ crashed while landing on Lake Ramadi in a sandstorm killing four crew members. This cover to Melbourne from Sittingbourne, Kent, has had the stamps washed off in the crash. An explanatory note, printed in Melbourne, was delivered with the letter. A scarce note.
