Dewoitine D.520, a beautifull deadly fighter.
Definitly for Rarity

North American P-51D Mustang
Fits Rainbow Dash confidence and skills very well

Supermarine Spitfire F. Mk 22
...well...her name is Spitfire too xD plus both are very fast and agile!

Fiat Cr.42
Very pleasent to fly, slow but ideal even for rookies, a reliable machine. Fluttershy would love it

Kawasaki Ki-100
For some reason , when i think in a country for Twlight, my first option is always Japan. Also twilight sparkle voice in japanese rocks so much!!

Messerschmitt BF-109G-10
One kick from applejack is more than enough in a fight. Same with the nose mounted MK103 30 mm cannon...

Lavochkin La-5FN
Same way that my mind fits Japan and Twilight, does with Pinkie and Russia. Or Soviet Union in this case. plays acordeon music

I almost added Spike with a P-39N airacobra but had no room in the transportation box xD
