Mans common transportation until the automobile was the
horse and buggy. Few remember the time before cars and expressways. The speed of
transportation has increased from the horse to 24,000 mph in space!
Automobiles
The first U.S. gasoline automobile was invented in 1885. By 1900, only one in
9,500 Americans owned a car. Today there are over 600,000,000 cars, trucks and buses in
the world! Americans spend over $91 billion on new cars alone! And $43 billion on used
cars! U.S. auto plants produced 6.0 million passenger cars and 5.7 commercial vehicles in
1996. [Japan produced 7.8 million passenger cars and 2.4 million commercial vehicles.] The
U.S. has over 3.9 million miles of public roads! Private automobiles carry 80.5% of all
intercity traffic.
Railroads
The U.S. railroad industry began in 1826 with the horse-powered 3-mile-long
Granite Railway used for hauling stone. By 1860, over 30,000 miles of railroad track had
been laid; by the 1880s, over 70,000 miles of track. Although railway passenger travel
continues to decline due to automobile and airplane travel, double stack freight trains
carry containers across the continent. Automatic Car Identification, a nationwide
computerized network, provides a system for quickly locating rolling stock. In 1979,
Japanese trains using magnetic levitation achieved a speed record of 321.2 mph.
Air and Space Travel
In 1918 the first U.S. airmail service began. By 1926 U.S. airlines carried just
under 6,000 passengers. Today, commuter air traffic is growing 6% to 10% a year, with over
1,315,269 passenger arrivals and departures worldwide in 1996. In 1982 U.S. air travelers
spent less than $15 billion. Today, over $25 billion is spent on air travel.
The Space Age began with the launching of the first satellite, Sputnik,
October 4, 1957. In 1969, the Apollo 11 mission landed the first men on the moon,
watched by live television audiences on Earth. The astronauts reached 24,791 mph during
their flight. The first space shuttle flight took place on April 12, 1981. By 1995, 65
flights had been launched. From 1957 to 1993, there were 3,569 successful space flights
worldwide.
