Development
The PW-4 was built for U.S. Navy Specification No. 96, calling for a carrier-based light fighter. This specification was eventually revealed as a cover for the Navy's actual desire for an airship fighter, the Curtiss XF9C. The XFA was a single-bay biplane with an all-metal fuselage and metal laminate skin. The construction of its fuselage was innovative in that instead of using lap jointing, the edges of each panel were bent inwards, with the rivets fastening them on the inside, instead of being visible on the surface. It had a gull-type upper wing which was fabric covered. The prototype was ordered in 1930, but the company was engaged in another reorganization, which delayed its work. Delivered for evaluations in 1932, it showed poor flying characteristics, including longitudinal instability and over-sensitive controls. General Aircraft increased the area of the tail surfaces and made other changes, then returned the prototype for more testing; but now the stability problems were worse. The plane would nose up with more throttle, but then drop its nose when the throttle was reduced. After another round of modifications, and some close calls, the plane was finally classed as unsafe and testing was abandoned.

Famous quotes containing the word development:
“I can see ... only one safe rule for the historian: that he should recognize in the development of human destinies the play of the contingent and the unforeseen.”
—H.A.L. (Herbert Albert Laurens)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
“I have an intense personal interest in making the use of American capital in the development of China an instrument for the promotion of the welfare of China, and an increase in her material prosperity without entanglements or creating embarrassment affecting the growth of her independent political power, and the preservation of her territorial integrity.”
—William Howard Taft (1857–1930)
