    The background music during engine startup is amplifying the power and strength of the b777 engine.

    I loved the transition to your engine-series background music when the animation shifted temporarily to the left engine start. I appreciate how you’re putting a lot of thought into the structure and flow of these videos!

    Another spectacular video, the quality of the video associated with the description of the system is brilliant. I can say that it enriches and facilitates learning far beyond the airplane manual.

    So much engineering ingenuity is taken for granted in our daily lives. These videos shed light on how science and engineering provide the quality of life that we enjoy.

    This is amazing. I felt like I should be taking notes, as there would be an exam tomorrow! This is drinking from a firehose level, nothing dumbed down for layman consumption.
  • @ZozoTravel
    Extremely amazing & informative video, thank you. πŸ™‚
  • @MarcPagan
    From a pilot, thanks for such well done research, and world class presentation. If the same people who did this presentation, taught my aircraft transition class/ground school, ...learning the aircraft systems during my one month stuck in a classroom would have been much more enjoyable :) ... and efficient, with regards to learning, and command of the information.
  • @sdas7731
    Excellent video. Learned a lot about apu.
