I really love airplanes. In real life, I work on aircraft as a mechanic, and I am also deeply intrested in aircraft and aircraft history. I really love the way this was put together, from the strain of flying the old byplanes to the types of characters to gas masks and there's a lot of space in here for some really good stories. It really allows players to zero in on the personal struggles of their own characters.

My one gripe was going to be with the plane builder. I was a little dubious about all these links to a program which may not exist in a few years, so I went to the plane builder and looked over all the rules. What I found was a fairly complex but well put together system (which is still in development) that allows anyone to build any plane.

And I do mean any plane (well, nearly)

Like I mentioned, the web app for the plane builder is still in testing, but it does work right now and has all of the aircraft in this book, but there's space to create your own whole aircraft with it. If you have enough time and access to a Jane's book or some other archive of WWI-WWII planes, I think you could probably make some of those aircraft from other Eras, or some Crimson Skies aircraft if you're into that universe. Really well put together so far.

I should back this up by saying you don't actually need the plane builder to play the game you can totally just play the game with the rules presented in the main book and the plane catologue and the weapons list. You don't need to bother with trying to build your own engines. The game stands on its own, but there's a highly crunchy system to let you homebrew some planes.
