I've got to say this is a weird one. It seems there could have (probably should have) been a more in-depth story but for whatever reason, we don't get it. The art was pretty, though, and I liked how the pilots risked everything in order to be able to fly. You also don't get too much characterization from anyone.

Basically this manga lacks everything except a premise for a feel good story centered around flying, don't think I would recommend it unless you enjoy flying, too. I liked it because it made me feel good about life.
