 The next day, Jackson personally led two of his unit's five concerted strafing assaults on the main Japanese convoy approaching Milne Bay.On 27 August, he and a fellow pilot each claimed a Zero; the Japanese fighters had been focussing on machine-gunning one of their own aircraft that had crash-landed following combat with a USAAF B-26 Marauder, presumably to prevent it falling into Allied hands, and were 'bounced' by the Australian pilots.His victory made Jackson an ace, the first from the RAAF in New Guinea.
