The Fokker D.XXI, you can’t call it a pretty aircraft. it was the main fighter aircraft of the Dutch airforce in 1940 and it put up a damn good fight against the superior Luftwaffe.
This one shows a pair of fokker D.XXI taking off from Ijpenburg airfield on May 10th, 1940, while under attack by Luftwaffe He-111s.

This one shows a D.XXI on a test flight. Quite an old image.
A Dutch Fokker D.XXI has shot down a Messerschmitt Bf109E-3, whose pilot is about to bail out. Again quite an old image.
