I follow both these channels and fall into the typical demographic. As a lockdown pass-time I got back into flight simulation as it coincided with the release of Microsoft's excellent latest software. I started watching last year to try and train my ear to understand radio language and learn more about modern flight systems.
I find them strangely fascinating. Not only are the videos quite long, but a lot of the content has a lot of similarity. It shouldn't work, but for me it does. I think the key is what makes each flight different: the journey, navigational and weather challenges and the calm way pilots like Max and Greg deal with them. I have always been interested in seeing how they captured the flights, but it's great to see the post workflow for the full picture. A thank you to Sam as the hidden person behind the scenes creating many happy hours of lockdown viewing!
