context_page_description: The Boeing 247, sometimes called the Boeing Model 247 was an American airliner. It is thought to be the first airliner to fully use advanced things like retractable landing gear, an autopilot and deicing boots.
  The Boeing 247 first flew on February 8, 1933. It started being used later that year. Later, planes became bigger and some had four engines. However, no big changes were made until Boeing made the Boeing 307 Stratoliner.
