I searched to see if anyone else had already made this suggestion, but did not find one. My suggestion would be to make Cockpit 1's height 2 instead of 3, to make them the same height as the passenger seats for the purpose of building. As you can see in the screenshot, I can't place a window in the space where it looks like one should be. Also the block I am using for the roof of my HV had to be placed differently over the cockpit than the rest. I know the other Open cockpit is already 2 in height, which I would have just settled for that, but when I attempted to use it, the first person view was so low, I could not see through the window and could only see the block in front of the cockpit.
