Inbound to the target, the weather was scattered cumulus from ground to 5,000' and clear over as the formation flew up the Warangoi River and arrived over the target area by 11:55am and turned over Tobera Airfield. The bombers caught a plane on the ground that exploded and strafed trucks. The formation was intercepted by approximately fifteen Zeros flying in groups of three to six. Intercepting, the F4U Corsairs claimed seven in air combat with the loss of three planes and two bombers damaged.

Returning, the formation flew via Kabanga Bay then towards Cape Saint George on New Ireland. Hanson attempted to strafe targets at Cape Alexander on New Ireland. While strafing, this Corsair was hit by anti-aircraft fire, crashed into the sea and cartwheeled on impact. When Hanson failed to return, he was officially listed as Missing In Action (MIA).
