After North Korea invaded South Korea on June 25, 1950, which sparked the conflict, General Douglas MacArthur, Commander-in-chief of the Far East Command, ordered the FEAF to carry out air raids on North Korea to prevent North Korean forces from overrunning the nation. Bad weather delayed further air actions until June 29 when MacArthur authorized FEAF attacks on airfields in North Korea. For the first time, B-26s of the 3rd Bombardment Group attacked Heijo airfield near Pyongyang, the North Korean capital, claiming up to 25 enemy aircraft destroyed on the ground.
