well i'm not a photographer...but on long exposure pictures you often can't see moving objects, i'm kinda suprised you can even see the strobes and beacon lights, typically they just blur into one solid streak of light...
Guess it does look kinda steep, but, this was a takeoff and not a landing, so, it'd be possible. That and you can't get a really good feeling of depth because there's no actual object to be seen, just the light flashes. Just noted that the picture was taken @ DSM, is that one a class C? kinda thought it was, if so...holding 200 could require the steep climb as well.
