  1. 1. 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.
  2. 2. 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 didnt 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.
  3. 3. 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.
  4. 4. Continue  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."
  5. 5. 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
  6. 6. Continue  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 worlds largest passenger airliner and due to its size, many airports needed to expand their facilities to properly accommodate it.
  7. 7. More Airplanes  Sukhoi SU-30 MKI Mig-29 Boeing 747 ILYUSHIN IL-76 C-130 HERCULES C-47 SKYTRAIN GLOBEMASTER III Airbus A330-223
  8. 8. 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.
