Aerial Combat at Pearl Harbor
Despite the effective Japanese counter-air effort, a few Army P-40 and P-36 pursuit ships got airborne, including some from the small, and untargeted, airfield at Haleiwa on Oahu's north coast. These shot down perhaps as many as eleven enemy planes of the second attack wave, losing four of their number in return, two while taking off and one to American anti-aircraft fire while returning to base.
In the midst of the raid, twelve unarmed B-17C and B-17E four-engine bombers arrived over Oahu after a long flight from California. Unaware of the events then unfolding at their destination, several of these were attacked. Though unable to fire back, only two B-17s were destroyed, both after landing, an early indication of the toughness of the "Flying Fortress" in combat.
Two Navy SBDs flying into Oahu from the carrier Enterprise, were also downed by enemy action during the raid. One of these may have been the victim of a mid-air collision with its opponent near Ewa Field.
