This anime aired with another one (Girly Air Force) but that one wasn't my cup of tea. So in a way, I watched this because I did not like that, and trying if this would end up to my liking. I liked the dogfighting scenes due to it reminding me of games like Ace Combat. That's what really got me, it has even some cliff missions, but I won't spoil any more than that. Now for each part: Story - I initially liked how each episode is like a mission but as it drove on, I found it lacking in some aspects like explaining why things existedas they are. They left me questioning even after finishing the anime. And I wanted to know more, but sadly it ended so briefly. A sample question you might have is, "Where's my water?" (No, I don't mean the tablet game with the bathing croc.) Although they explained it somehow, it's quite "Eh, if you say so." kind of thing.

Art - I read reviews complaining about 2D/3D swapping and causing people to drop the anime. I didn't really notice that until I read them. But even then, I didn't have any problems with that. I like how they look in general although I would very much prefer them using more uniform-like attires and not fanservice-y considering the pilots are not just some ragtag people who stumble upon a plane one day and learn how to fly them. I mean, some of them are mercs, contractors, and etc. For the planes, the planes look cool, enough said.

Sound - I never really cared much aside from guns, cannons, and planes getting shot down. So yeah.

Character - They are quite unique in their own way and it *would've* been nice if they all got explored more. I know it's not possible due to being a 12-ep anime. Some secondary chars are quite fun (Captain Dodo is OP, I know. And Johnny too.). You would grow to hate a specific jerk by the end of the anime. And because of that, I know they served their purpose.

Enjoyment - I did enjoy watching this, so much that I pondered for days whether or not I should write a review for it. Most of my reasons for my enjoyment is already mentioned above.

Overall - It's good. It won't be a waste of time for people wanting to watch planes, watch planes, and watch more planes. But that's that for me.

Complaint that don't seem to fit on the above:
How come they don't blow up the planes? Like really? Is everyone so good at aiming at a fast flying object while riding another fast flying object? All the while NOT HITTING any pilots, or at least causing the planes to explode. Their accuracy puts WW2 pilots/guns to shame.
