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 1980s 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
airports must also have customs areas and currency exchange counters and so
on. A. Airport services B. Training of
pilots C. Beginning period D. Rapid growth in
