Actually the planes that hit the twin towers were a pair of Boeing 767-300s, a twin engine medium-long haul single deck wide body airliner. The plane in this gif is a Boeing 747-100, a four engine long haul multi-deck wide body airliner. The 747-100, sir, was not involved in the attacks of September eleven, 2001. Please, before you post, please check any aircraft related information for fear of offending me, allanisgreasy, or another aviation expert with your incorrect memes
