Boeing 737
In 2011, Boeing said that it was working on the 737 MAX program. Boeing will make three types of 737 MAX. These are the MAX-7, MAX-8 and the MAX-9. The MAX-7 will replace the 737-700, the MAX-8 will replace the 737-800 and the MAX-9 will replace the 737-900ER. The 737 MAX will have CFM International LEAP-1B engines. The wheel in the nose of the plane has been made longer. Deliveries are supposed to start in 2017. Southwest Airlines became the launch customer on December 13, 2011. Lion Air and others have made orders for 737 MAX planes.
