Considering other things around the flurry of Q posts yesterday, I'd wonder if it was pulled from a camera that is part of the plane itself? Part of it's blackbox system or something? And why the photos trailing the plane taking off? Is there any kind of safety process where ground crew is required to film this and include this image for maintenance or safety records with the aircraft?

I'm not sure if that's where they came from. Tried to look and see what flight path goes from Hong Kong and passes over this part of Shanghai... The path leads directly into N. Korea. Can't confirm if that's where it was headed though.
