Thank you for being a little more civil this time with your comments.
Here's the thing. Everything I have said with all of my various theories is speculation, and I have never claimed otherwise. The whole point of being given a taste with the trailer and the footage is so that we can look forward to playing the end game, as well as using our imagination to try and guess certain elements of what we can expect. For me, this is something I really enjoy doing. Trying to fill in the gaps and painting a more complete picture.
All I have done is put forward what I think happens during the tutorial and the main quest, but that does not mean that I am suddenly guaranteed to be correct. As for some of the finer details, different people see different things when watching the footage, and this is to be expected. One thing I have tried to do is look at what may happen in such extreme circumstances. For example, no matter how well trained, who knows how a soldier or group of soldiers will react when they have just witnessed a nuclear detonation over what could be their home town. So they might have taken off in the vertibird even though it would not be a very sensible thing to do. In extreme circumstances, people react in unusual ways. Note that in the post-war footage, we cannot actually see whether or not the vertibird is still there, because the camera does not pan round enough.
So let's all continue to speculate and look forward to the final release in November. For the record, I actually really like your idea about the brewery
