The decades following the First World War saw aircraft designers pushing the boundaries of aeronautical technology, moving the industry forward at a rapid pace. With new commercial markets opening up, it was the visionaries who held the key to success. Each invention promising a future filled with endless possibilities.
Traditionally, regulators had insisted that all passenger aircraft be powered by at least three engines. But the development of more sophisticated airplanes eventually made twin-engine, long-distance travel feasible. A new standard was introduced, known as Extended-range Twin-engine Operational Performance Standards, or ETOPS.
The Boeing 737 twin-engine jetliner was to become Boeing's greatest success. It had one of the lowest approach speeds of any jet transport, a great asset when landing at smaller airports with shorter runways. It also required minimum equipment for use in refueling. However, despite all its advantages, the 737 was soon overshadowed by the new, improved 747 Jumbo Jet.
