The Nieuport 24 (or Nieuport XXIV C.1 in contemporary sources) was a World War I French sesquiplane fighter aircraft designed by Gustave Delage as a development of the successful Nieuport 17.
The Northrop XP-56 Black Bullet was a unique prototype fighter interceptor built by the Northrop Corporation. It was one of the most radical of the experimental aircraft built during World War II. Ultimately, it was unsuccessful and did not enter production.
