The first was 420 ft (128 m) long with a gas capacity of 400,000 cu ft (11,200 cu m)-10 times the size of Giffard's pioneering airship, and 60 times the volume of Santos-Dumont's Number 1. The Zeppelin's most striking feature, however, was its size. The engines, crew, and passengers occupied small pods suspended from the underside of the hull. Tall, narrow gas bags, separated by frames and maintenance catwalks, filled the interior space. Designed by (and named for) Count Ferdinand von Zeppelin (1838-1917), the new airships had rigid, cigar-shaped hulls built of metal frames braced by wires and covered by fabric. Beginning in 1900, however, airships of a radically different design began to emerge from Germany. Santos-Dumont's airships, like virtually all of those built before them, were non-rigid: the pressure of the lifting gas maintained their shape. The growing power of gasoline engines gave Number 1's successors greater speed and maneuverability, making them the first truly practical airships.

In 1898 Alberto Santos-Dumont (1873-1932) flew a gasoline-powered airship, Number 1, that produced the same 3 horsepower as Giffard's steam engine, but weighed 80% less. The gasoline engine, developed in the 1890s, provided the kind of power-to-weight ratio airships needed. His 350-lb (159 kg), 3-horsepower engine drove the 44-ft (13.5 m) airship at little more than 5 mph (8 kph), making operation in even a gentle breeze impossible. The first successful airship was built and flown in 1852 by Henri Giffard (1825-1888), then Europe's leading steam engine designer. The problem, as many discovered, was finding a light, powerful engine. The two basic elements of an airship-a balloon for lift and an engine-driven propeller for power-were readily available to nineteenth-century designers. Airships survived, after 1940, in the significant but narrowly defined niche of aerial observation platform. World War II smothered any hope of a quick revival, and produced a new generation of airplanes superior to any foreseeable airship.

The promise of airships dimmed rapidly in the 1930s, however, after a series of spectacular crashes tarnished their reputation. Germany, Great Britain, and the United States all built airships after World War I, and all saw airships as a key part of aviation's future. Airships reached technological maturity by 1920 and were, for the next two decades, superior to airplanes for long flights with heavy payloads.

Lighter-than-air airships and heavier-than-air airplanes both became practical around 1900, and coexisted for the next 40 years.
