Pilot History
Hemsworth had flown a raid over Rabaul on the night of February 3-4 and his Catalina was heavily damaged—possibly by FPO/1C Hiroyoshi Nishizawa, who was flying a A5M4 Claude (a few of them teamed up with the searchlight crews) and claimed a Catalina that night. Hemsworth did an amazing job of getting the plane back to Port Moresby on one engine. The total event lasted more than 24 hours including a night landing off Salamaua.
