Provided by the RAF during World War II for Qantas to operate non-stop flights between Australia and Sri Lanka (Ceylon). At the end of the war, the RAF ordered G-AGFM scuttled, not scrapped. A bridge over the Swan River prevented it being towed to sea. So the RAF ordered the aircraft by made airworthy again. On February 26, 1946 it was flown to the sea near Rottnest Island where it was sunk with explosives. Except for a wingtip float which had detached and drifted off. It had to be dispatched with a tomahawk. Photo from: Hudson Fysh Collection/State Library of New South Wales

Possibly one of the most interesting/informative exhibits in the whole of the National Museum of Naval Aviation is this PBY cutaway. Fascinating to see the different crew positions and how they were able to do their jobs.
