Curtiss CW-20 Commando
The Curtiss C-46 Commando was a large, twin-engine cargo transport that carried significantly more freight than its more famous contemporary, the Douglas C-47/DC-3. It became legendary for flying 'The Hump' — the dangerous supply route over the Himalayas from India into China during the Second World War, when overland routes were cut off. Its distinctive, rounded double-bubble fuselage cross-section gave it more usable cargo volume than a simpler circular design. A handful remain airworthy today, flown by warbird enthusiasts and preserved as flying memorials to that wartime airlift.
