Yes, the main cabin door opens as well as the overhead window and the side windows. And yes, that changes the sound. Each window makes for a different sound change because it's near a different engine. Opening all three gets it "as loud as it gets". Which is too soft in my opinion and the opinion of many others. The sound design is top notch except for the volume issue, which I think they'll fix in the first update.
Overall I'm very pleased, it's well done except for a few minor issues, it has character, and it's fun to fly for anyone into classic aviation. The 1939 version is delightfully weird but functional, with a 1930s style AP that will only hold a heading, and a version of German 1930s radio navigation.

Hi Dutch,
how did you get the main cabin door to open?
Cheers,
