The first great ships of the air were the rigid dirigible balloons pioneered by Zeppelin, which soon became synonymous with airships and dominated long-distance flight until the 1930s, when large flying boats became 

popular. After World War II, the flying boats were in their turn replaced by land planes, and the new and immensely powerful jet engine revolutionised both air travel and military aviation.

In the latter part of the 20th century the advent of digital electronics produced great advances in flight instrumentation and "fly-by-wire" systems. The 21st century saw the large-scale use of pilotless drones for 

military, civilian and leisure use.
