I've checked the Turkish Airways flight from Istanbul. It is on its way to pick us up. We will be aboard TK 75 as it returns home as TK 76. As sunset in Vancouver is 5:53 tonight, we should be headed through security at the airport at about the time of sunset.
Our flight is supposed to depart at 8:05 pm and that appears very possible as the plane heading this way is about a half hour ahead of schedule at present. However, it's only between Norway and Greenland now.
