This is possibly one of the most underrated animes out there. Probably because it was never completed. But it really had potential.
Even though the story never took off because it didnt have enough time. You get to know the characters and enjoy watching them get to know each other and learn new things.
And unlike most plane anime this one doesnt focus on killing, instead they are an airshow plane group. That makes it a lot more interesting for me.
With only 7 episodes you don't go very far storywise, but you do get to have some fun along the way. Don't expect an ending because there isnt one.
