Probably taken on the flight line on Eniwetok, MB-6 awaits its next mission.  Each of VMB-613's aircraft had two assigned aircews.  MB-6's two aircrews were that of First Lieutenant Robert E. Love and First Lieutenant William J. Love, hence the name, "Love Bug."   First Lieutenant William J. Love and his crew were killed when this aircraft was shot down on a raid over Ponape on February 6, 1945.
