Additional Documentation: ORIGINAL RECORDS ARCHIVED AT ODP, NAVIGATION ON/OFF SITES MAY BE INACCURATE DUE TO INSUFFICIENT COURSE, AND SPEED DATA. DUE TO COMPUTER CRASH ON THIS LEG, DR SPEED DATA WAS ESTIMATED FOR MOST, OF THE LEG. DRIFT SPEED AND HEADINGS ARE NOT ACCURATE. FINAL NAV BEST ESTIMATE, 05th/07 course change to 073 estimated to be at 1230. Exact time not given. 25th/08 course change to 053 estimated to be at 1530. Exact time not given.
