The Curtiss F9C Sparrowhawk is a light 1930s biplane fighter aircraft that was carried by the United States Navy airships USS Akron and Macon. It is an example of a parasite fighter, a small airplane designed to be deployed from a larger aircraft such as an airship or bomber.
Chengdu J-9 (Chinese: 歼-9) was a designation assigned to a Chinese interceptor aircraft that never progressed beyond initial studies. The J-9 project was abandoned in favour of the Shenyang J-8, which was a safer technological bet for the limited Chinese aviation industry of the 1960s and 1970s.
