a brief of airplanes

2. History of airplanes
Hot air balloon

 The first successful air flight was in a hot air balloon. In
1783 a few men invented the first flying machine by
making the hot air balloon. A hot air balloon is a balloon
filled with heated air. Since heated air is lighter than cool
air, the balloon would rise into the sky. The pilot would
ride in a basket attached to the balloon and control the
height by adding and subtracting more heat.
 The problem with hot air balloons is that you can not go
the way you want. If the wind is blowing west, that
means you would have to go west, too. During the Civil
War hot air balloons were used by the armies to look at
enemy troops.

3. First Airplanes

 The first airplane that was flown was a glider. A glider is
a non-motorized flying machine (and very hard to
control.) Early gliders were launched from high places
like cliffs and floated on the wind to the ground.
 A man named Sir George Cayel made the first glider that
actually flew. His first glider didn't have passengers or a
pilot. It was too small and could not fit anyone in it. He
made another that flew across a small valley. This glider
was not launched from a cliff.

4. The Wright Brothers

 During 1890 while Orville and Wilbur Wright were
working in a bicycle shop, the Wright Brothers got
interested in flying. They learned that bicycles that
were closer to the ground were faster. They read all
the books they could find about airplanes to learn
more. The Wright Brothers improved the glider and
at last the made a engine propelled glider.

 In December of 1903, the Wright Brothers became the
first people to successfully fly a plane with a person
in it. The plane flew one hundred twenty feet and
flew only about twelve seconds. They had three
successful flights that day, but Wilbur made the
longest flight of 892 feet and stayed up for about 59
seconds. In 1903 the Wright Brothers made their first
powered airplane that they named the "flyer."

6. Types of airplanes

 Modern airplanes are divided into five main types:
 1. Commercial Transport Planes
 2. General Aviation Planes
 3. Military Planes
 4. Sea Planes
 5. Special Purpose Planes


 The Boeing 747 is a four-engine jet that unlike most
airliners, can carry
 1. 1,000 passengers
 2. Less than 200 passengers
 3. More than 400 passengers
 4. 50 passengers
 The Airbus A380 is a double-deck, wide-body, four
engine jet airliner. It is the world's largest passenger
airliner and due to its size, many airports needed to
expand their facilities to properly accommodate it.

9. Facts about airplanes

 A Boeing 747 stands at almost a 7 floor building height!
 Jet fighters fly at the speed of 1235 km/ hr. or 768 m/hr.
 Civilian passenger jets cruise at between 30,000 and 39,000 feet.
Military aircraft can attain greater altitudes.
 A new Gulfstream G550 is priced 59.9 million US Dollars and is
considered as the most expensive private jet to date. British
billionaire Sir Philip Green is one of the proud owners of the
G550.
 Official records point to the Lockheed SR-71 Blackbird as the
world’s fastest, manned jet aircraft. It can travel with a speed of
2,194 mph or 3,530 km/h
 The 747 fleet has logged more than 42 billion nautical miles
(77.8 billion kilometers), equivalent to 101,500 trips from the
Earth to the moon and back.
