I'm still on an airplane kick. I have always been interested in the Boeing -377 Stratocruiser. It's based on the B-29 bomber with an enlarged double deck fuselage capable of holding between 63 to 84 passengers depending on if the ship had births. It was one of the last radial reciprocating engine luxury airliners and only 55 were built. There was also an enlarged freight version called the Guppy and the Air force used it as the C-97. BOAC and AOA operated this aircraft and PAN AM named it a Clipper like its earlier long range aircraft, the B-314 China Clipper. The introduction of the jet engine British Comet and the Boeing 707 brought an end to the operation of the B-377 in 1963. More info on Wikipedia. https://en.wikipedia.org/wiki/Boeing_377_Stratocruiser
