The vast patchwork of airfields that were a legacy of World War II rendered obsolete the commercial flying boats.
They were replaced by multi-engined landplanes with pressurized passenger cabins, although these, too, soon gave way to the unprecedented speed and comfort of the first turboprop and pure-jet airliners, German wartime research into high-speed aerodynamics had pioneered innovations such as swept wings and podded engines, ushering in the era of supersonic flight. There was also tremendous experimentation with new technologies. In military aviation, the jet engine revolutionized the performance of front – line light fighters and bombers, allowing them to climb higher and fly faster than ever before. The greatest developments of this era were supersonic transport aircraft, high-capacity widebody airliners, and vertical take-off aeroplanes. However, piston-engined aeroplanes were still widely used: as well as conducting survey and agricultural work, they were flown by smaller airlines which were being set up in previously remote parts of the world.
