I would say that one of the things that kept me interested in the game learning about that airship. I put off doing that quest line for a long time for fear of disappointment. When I did it and learned that the Brotherhood built ships like that in the past and they were lost. That had to be the best part of Fallout 4 for me. Basically it confirms the introduction of Tactics is canon.
I also like the Brotherhood in Fallout 4 more than I did in Fallout 3. I guess that's because as you said Arthur has them https://www.youtube.com/watch?v=I4acAV46vvQ
