To retain communication with the isolated Australia from the British Empire during the World War II, Qantas Airways introduced a top-secret non-stop service between Perth and Ceylon. The airline maintained radio silence and navigated only by stars.
Operating once in a week, the secret carrier could travel as long as 32 hours and nine minutes. It was called ‘Double Sunrise’ flight because while on board, one could see the sunrise twice. The aircraft was modified with extra fuel tanks with a capacity of almost 2400 gallons. Equipment like de-cing insulation, was taken off the plane to make it lighter.
The flight could accommodate only three passengers at a time, with a few bags of mail, micro-filmed to reduce weight. As per Conde Nast Traveller, the flight made a total of 271 trips during the time of war.
