Basically what you’re asking for is an avatar to use in the third person, similar to games like GTA. Its been asked for before by various people here. Who knows maybe someone will do it some day. The SDK would need to be able to support it. We do already have animated ground crew so we’re already somewhere on the road to be being able to do it. Making them user controllable is a whole different matter though.
Personally I’d quite like to see it. I think it would be quite good fun and it would indeed be great for making movies. I’m sure it would come in for a lot of criticism from the ‘its a flight sim not a game’ brigade.
On a similar-ish note I’d love to see greater variety in the pilot avatars and Asobo should really make them visible when in the cockpit by default. There are a few mods out there for doing it. I’m quite a fan of having some company in the cockpit, especially in VR.
