It was a lumbering World War II flying boat, cruising at 125 mph across a hostile ocean for up to thirty-three hours at a stretch &mdash; long enough for the handful of passengers aboard to watch the sun rise not once, but twice. They called it the Double Sunrise.<\/p>\r\n\r\n<p>For two years, Qantas Catalinas flew this secret route in complete radio silence, navigating by the stars, to reconnect Australia with a Britain cut off by war.

Something had to replace it, and it had to avoid Japanese-held territory entirely. The answer, agreed in secret between the two governments, was audacious: fly straight across the Indian Ocean, non-stop, in flying boats.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img data-opt-id=745245373  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:Jza1.c82e\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/07\/pby-catalina-flying-boat.jpg\" alt=\"A Consolidated PBY Catalina flying boat\" style=\"width:100%;height:auto;max-width:100%;display:block;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">The Consolidated PBY Catalina &mdash; slow, rugged and enormously long-legged, exactly what the impossible route demanded.

They were stripped of every spare pound of weight and filled almost to bursting with fuel; the margin between the aircraft&rsquo;s range and the length of the route was razor-thin. There was no radio &mdash; long-range wireless simply couldn&rsquo;t reach across that much open ocean &mdash; so the crews flew in silence, fixing their position by the stars.<\/p>\r\n\r\n<p>Each flight left Western Australia in the evening, so it would cross the most dangerous stretches in darkness, and pressed on for a day and a night and most of another day. Because the westbound trip lasted so long, passengers saw two dawns break over the water. The record crossing took 32 hours and 9 minutes &mdash; a mark for a scheduled passenger flight that still stands today.<\/p>\r\n\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/ouUKqF8fUNc\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\r\n<p style=\"font-size:13px;color:#777;font-style:italic\">Restored wartime footage of PBY Catalinas at work.<\/p>\r\n\r\n\r\n<div style=\"background:#f8f9fa;border-left:4px solid #5C91FF;padding:20px 22px;margin:18px 0 24px;border-radius:0 8px 8px 0;font-size:16px;line-height:1.7;display:flex;gap:20px;align-items:flex-start\"><div><em>&ldquo;Those who flew on the original Double Sunrise flights were true aviation pioneers.&rdquo;<\/em><div style=\"margin-top:10px;font-size:14px;color:#555\"><strong>Luke Peters<\/strong> &mdash; aviation writer, AeroTime<\/div><\/div><\/div>\r\n<h2 style=\"padding-top:22px\">The Secret Order of the Double Sunrise<\/h2>\r\n\r\n<p>Space was so tight that a typical flight carried just three passengers and a few dozen kilograms of diplomatic mail.

It was on these flights that Qantas first painted its now-famous flying kangaroo on an aircraft, and the operation was officially christened the &ldquo;Kangaroo Service.&rdquo; Faster Liberators and then converted Lancaster bombers eventually took over, and the Catalinas were quietly scuttled at war&rsquo;s end.<\/p>\r\n\r\n<p>But the name never faded. When Qantas set out to fly non-stop from Sydney to London &mdash; a goal it expects to reach around 2027 &mdash; it called the programme &ldquo;Project Sunrise,&rdquo; in tribute to the Catalina crews who did the impossible first. Their duration record has stood for over eighty years, and probably always will.<\/p>\r\n\r\n<p><em>Sources: The Double Sunrise (Wikipedia); Luke Peters, AeroTime; Simple Flying; <\/em>Return of the Catalina<em> (2015); Qantas Founders Museum.<\/em><\/p>\r\n\r\n\r\n<div style=\"background:#f0f4ff;border-left:4px solid #5C91FF;padding:16px 20px;margin:32px 0 8px;border-radius:0 8px 8px 0\"><p style=\"margin:0 0 8px;font-weight:600;color:#333\">Related Posts<\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/pacific-clipper-round-the-world-1941-1942\/\">The Pan Am Clipper That Flew Home the Long Way<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/catalina-ii-flying-boat-pan-am-first-customer-2026\/\">The Catalina Flying Boat Rises Again<\/a><\/p><\/div>\r\n","protected":false},"excerpt":{"rendered":"<p>The longest passenger flight ever operated was not a modern jet gliding from Singapore to New York.
