The story was really nice, engaging, covering today's world like depression, hiding feelings. There is lot of things to learn like selfless love, sacrifice, ideology, lessons. The actors did there job very well.
But the direction and animation lacks behind, the knowledge about aviation that is needed in the show was lacking behind, the director must have done research about the procedures and rules more. There are loopholes making it look cheap, low budget kind of thing.
A nice series to watch otherwise.
