I watch a youtube channel called Mustard. Mustard is a channel that makes history videos about different inventions. In most of the videos I watched, he talked about aircraft. for example, in the most recent one, he explained the history of giant flying boats. It is called: what happened to giant flying ships? That video talks about when giant flying aircraft first came out and what they had been used for, and why they don’t use them anymore. I like the videos a lot because he makes the videos very interesting because he makes a model of the subject he is talking about, and that sometimes he adds a bit of humor to the video.
