Your reply only cement your "5-cent gang" reputation even more, and worse trying to insult our intelligence...first of all that shipyard is a civilian / commercial establishment and not a military base; next, commercial airline flight path is a whole another kind of matter compare with private aircraft (including helicopters) flights, in China currently all such flights requires such flight plans to be prior submitted for approval, not like in US just submit to FAA for records - China's airspace is the most restricted in the world due to historical reasons, though there's an official roadmap to open up the skies but the most resistive forces against it comes from the PLAAF.
Next, you can't possibly take photos from your window seats if the airliner flies straight and level, it needs to be banking and climbing / descending to get the angles right, that means the airliner isn't flying directly over the shipyard but on a route off by an angle, during its climbing / landing phase.
Thirdly, if you've ever flown on an airliner you should have some idea how cramp the seats are, and how unfavorable the lighting conditions for such photo-taking can be, not to mention ruling out the use of DSLR or even the Micro Four Thirds lens camera, the most viable of tools would be small DC or smartphone camera; now combine with the kind of think plexiglass of airliner's window and a few seconds worth of photo-taking opportunity, that's why such pics, if successfully taken, are usually so blur.
It's your bad luck that there're Chinese-specking members in this forum who can immediately see through you. Please reserve your political bravado in mainland China's forums, it'd only do ill service for China.
