Design and Development
The Fokker D.XXI was a low-wing monoplane with a fixed spatted undercarriage. Following standard Fokker design practice of the period, it had a steel tube fuselage covered in large part by fabric, with wooden cantiliver wings. Power was provided by a Bristol Mercury radial driving a three-blade two-pitch airscrew. When it entered service in 1938 it was a quantum leap forward for the Dutch Army Aviation Group, whose fighter force had until that time consisted of aging biplanes with open cockpits. The new Fokker proved to be an extremely sturdy aircraft capable of attaining a speed of 700 km/h in a dive.

Famous quotes containing the words design and/or development:
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the child’s mind and personhood.... Parents who enter into a dialogue with their children, who draw out and respect their opinions, are more likely to have children whose intellectual and ethical development proceeds rapidly and surely.”
—Mary Field Belenky (20th century)
