Ok so on some of the planes i didnt think you could have doors open parked like saab340 cj4 pc12 but i actually was able to do this but i dont know how i did it on them. I fooled around with external view and other settings an doors remained open even cargo door on saab340 whats the secret procedure cause i made it work somehow?? Second question is somehow i got passengers to load on planes and then they dissapeered sometimes it works somehow is there exact method to this?
