Austr. Aeronautical , Maj Davis shows left pencil line as PQ expected return course to Biak, this about 145 degrees, upper line estimated course ,actual course and approx position when last heard from, which Davis must take as 1855 hrs, last Mayday, this course line is almost dead on124degrees , the same course they departed target on at1215 hrs., target was Leyte Gulf, distant 1200 n m.frm posit. shown. On Equator. and 137 E. Ibeieve Davis off. My calculations , really speculation is PQ missed Palau Is. Waypoint, actually to the Northeast of that Is. Group on. Course of about 120 or so and 1st mayday at 1829 hrs. Places them at 1deg. 15 min. N, 138deg. 55 min E which is for your reference nearly 2 inches E by NE from 0 deg, 137E, the final posit. On Davis' pencil line. Irian NG coast in view for you in lower right hand corner. Thus if PQ 1829 then swings to a course of 170 they landfall at Sarmi vicinity. Mayday 1829 running out of gas, only chance is go south to hit a coast, then bailor ditch in surf on beach. PQ is now distant about 120nm. From. You NG coast , 30 min. at 250 knots so mayday 2 at 1855 hrs. Fits. Then they bail out or ditch. They bailed out. It is pitch dark at these latitudes by 1815 hrs or so, and Rundle found the wreck in a mangrove swamp. Fate after that, for all but Julian and Rafael, a mystery.
