His target audience is not the highly technical, but the public at large - including children. He's a space ambassador in that he wants to get the current and upcoming generation excited and learning about space.
With that said, he has been able to get in-situ interviews with rocket company CEOs including his amazing 2 hour almost single take video tour with Elon Musk [0] where I was able see Elon comfortable in speaking much more deeply, candidly, and enjoyably than with any interviewer/reporter prior. Tim Dodd is no professional engineer but he really knows his stuff. His personality helps bridge the gap between the highly technical and the layman.
Well, after spending eight hours working demanding jobs, be it physical or mentally, everyday people usually like to spend their free time with something a little more relaxing, and for most people that isn't reading documentation or reading highky technical engineering papers but rather watching a highly enthusiastic guy try and share his joy of rocket science.
That’s a good point. I’m not an engineer yet I prefer there be more description and less personality shining through; but you make a good point about target audience. And as you say he prepares for the material and does well to understand the experts.
He actually researches history, has contacts with many important people in areospace and actually managed to all the CEO from all the companies that had reached Orbit about the topic, Musk, Bruno, Beck. Since that video he also talked to it with the CEO of Firefly (that used to develop a spike and was propulsion engineer at SpaceX).
If you think you are to good to hear from those people then maybe you should get of your high horse.
Just because its not designed for only engineers doesn't mean it shouldn't be recommended. Find me a better video or article about areospikes.
A personality driven channel versus engineering
