In which war did jet aircraft fight each other for the first time?
World War 2
First Indochina War
For the initial months of the war, the P-80 Shooting Star, F9F Panther, and other jets under the UN flag dominated North Korea's prop-driven air force. The Chinese intervention in late October 1950 brought MiG-15 Fagot to battle, one of the world's most advanced jet fighters. MiGs were often steered by well trained Soviet pilots, so the aerial warfare continued till the end of the war.
