The fist time, the Boeing arrived from Darwin (YPDN) as RON900, before continuing on to Nauru (ANYN) with the same Flight Number.
During the late evening, NLK came back again from Nauru as ASY966. After a one hour stopover, it continued on to Darwin, before departing to RAAF Base Curtin (YCIN) and returning to Darwin at 2:00am. All in one day!
