Joseph Christopher McConnell Jr. was a United States Air Force fighter pilot who was the top American flying ace during the Korean War. A native of Dover, New Hampshire, Captain McConnell was credited with shooting down 16 MiG-15s while flying North American F-86 Sabres. He was awarded the Distinguished Service Cross, Silver Star, and the Distinguished Flying Cross for his actions in aerial combat. McConnell was the first American triple jet-on-jet fighter ace and is still the top-scoring American jet ace.

The Mikoyan-Gurevich MiG-15 is a jet fighter aircraft developed by Mikoyan-Gurevich for the Soviet Union. The MiG-15 was one of the first successful jet fighters to incorporate swept wings to achieve high transonic speeds. In aerial combat during the Korean War, it outclassed straight-winged jet day fighters, which were largely relegated to ground-attack roles. In response to the MiG-15's appearance and in order to counter it, the United States Air Force rushed the North American F-86 Sabre to Korea.
