Query: it'll never get off the ground

The 747 video, produced in 1989 is incredibly dated, with poor video quality and too much background information on the Boeing company and not enough on the plane itself. The 777 segment reuses much of the same content and has many glaring errors where the voiceover does not match the video. For example: the British Hermes airliner is discussed as footage of a Lockheed Constellation is shown, and the manufacturing process of the 777 is discussed while showing footage of a 747 under construction. It's obvious that the producers of the 777 segment did not bother to research their subject matter and merely hacked the show together with footage they had available to them.
