  2. What is it? • The Boeing 747 is a widebody commercial airliner, often referred to by the nickname Jumbo Jet. It is among the world's most recognizable aircraft,and was the first widebody ever produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was two and a half times the size of the Boeing 707,one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.

  3. How does it fly? • A plane flies by the aerodynamic shapes on the plane. The wings are shaped so that high pressure is made above the wing so the air has to move faster causing lift. • Flaps are mounted on the end of the wing. These slow the plane down for landing bo extending down and up. • Aileron work on the wings by extending either down or up. These make the plane bank to the left or right. • Elevators are also flaps that extend up or down to make the plane go up or down. These are mounted at the back of the plane. • The rudder is also a flap that moves from left to right. This makes the plane turn left or right.
