Recommend me shows with crazy planes/crazy flying shit...and no giant robots.
Steampunk: The Animation
sky girls - medium sized robots
simoun - medium sized thingys
strike witches - flying lolis
Magical girls do not count.
Also, I forgot which Leiji Matsumoto film/series that was...and also Area 88/UN Squadron
OP already said no robots. (Although the Vic Vipers in sky girls sorta are good. Speaking of Vic Vipers...)
In before every Ghibli movie ever created
OH E A
OH E O
Interstella 5555 has a crazy FLYING GUITARSHIP
FRIENDS FOR LIFE THROUGH THICK AND THIN, ON ANOTHER TALE SPIN!
>>simoun - medium sized thingys
Lesbocopters for the win!
Unfortunately there's little in the way of crazyplanes (as far as my admittedly limited knowledge goes) that hasn't been mentioned already or does not reduce to giant robots.
Nothing is more awesome than having the most GAR bear in all of Disney be by far the most GAR pilot in all of Disney.
