  • Wright Brothers

    Wright Brothers
    The Wright Brothers created the first powered aircraft, named Kitty Hawk, which weighed 625 pounds and used an 8 horsepower engine with speeds of about 25 miles per hour. https://airandspace.si.edu/exhibitions/wright-brothers/online/fly/1903/designing.cfm

  • Invention of automatic gyro-stabilizer

    Invention of automatic gyro-stabilizer
    The invention of the automatic gyro-stabilizer led to the creation of auto-pilot. It was made by Lawrence Sperry, and it uses sensors to keep the aircraft traveling straight. http://www.historynet.com/lawrence-sperry-autopilot-inventor-and-aviation-innovator.htm

  • Invention of Radial engines

    Invention of Radial engines
    Radial engines are the reason planes can fly how they fly. When they were introduced, they allowed planes to fly faster and longer, making them a very important part of our current success with aviation. Air-cooling and the lightweight of the engine allowed for bigger and faster airplanes. http://science.howstuffworks.com/transport/engines-equipment/radial-engine.htm

  • First Passenger Aircraft

    First Passenger Aircraft
    The Boeing 247 was the first passenger plane capable of carrying 10 passengers. It had a twin-engine and a retractable landing gear. It had a top speed of 200 miles per hour, and it could fly up to 800 miles. It is currently on display at the National Air and Space Museum in Washington D.C. https://airandspace.si.edu/collection-objects/boeing-247-d

  • Boeing 747

    Boeing 747
    The Boeing 747 was another passenger airplane invented by the aeronautical company Boeing. It has a wide body, and is run by 4 engines lying below the wings of the aircraft. The plane is considered one of the most successful airplanes ever produced, because it satisfied many of the passengers who flied on it, which is why it is still in production, regardless of the age of the design. http://www.boeing.com/commercial/747/

    Boeing 777
    The Boeing 777 was another successful jet made by the company. It was also the first jumbo jet made by the company that was aided with the help of computer models as well as human engineers. It uses one of the world's most powerful engines, and is one of the most fuel efficient planes on the market. It is run by two engines capable of 115,000 pounds of thrust each. http://www.boeing.com/commercial/777/
