1.
Airplanes are used to carry passengers, cargo and mail. Air transport companies
operate scheduled airlines and non-scheduled services over local, regional,
national, and international routes. The aircraft operated by these companies
range from small single-engine planes to large multiengine jet
transports. 2. The first air passenger services began in 1910,
when dirigibles began operation between several German cities. The first
scheduled airplane service to carry passengers began in the U.S. in 1914.
Several experimental airmail flights took place in India, Europe, and the United
States before World War I, but air transport service did not become a true
business until after the war. 3. During World War Two,
intercontinental air transport became firmly established. After the war, the new
long-distance transports with advanced facilities were increasingly able to
avoid storms and strong wind and make flights more economical and consistent. A
new generation of "jumbo-jet" transports began operations in 1970, and the
supersonic transport entered passenger service in 1976. 4.
During the 1970s the number of domestic passengers on U.S. airlines increased
about 78%, and during the I980s the figure was up about 58%. In 1990 there were
41.8 million international passengers, the figure was a 75% increase over 1980.
The total cargo flown by U.S. airlines almost doubled during the 1980s, from 5.7
billion to 10.6 billion ton-miles in 1990. 5. Major airports
provide a wide range of facilities for the convenience of millions of travelers.
These range from such basic services as ticket-sales counters and restaurants to
luxury hotels, shopping centers and play areas for children. International
