I played around with the hangar picture. I'm not sure I'd use the term "quite a bit", I was able to straighten it by rotating clockwise 0.8 angle. But anyway then I stared at the photo as a whole and it really doesnt look that bad. The roof of the hangar will slope down to the right a tad if rotated but it is on an angle to you so that is not unexpected. Furthermore, the famous "FLY DELTA JETS" sign is a little crooked too, rotating .8 makes the top of that sign dead-on-balls level. so I'd have to side with the Screeners here.
As for the mercury vapor, raising the input amount of the red color channel to about 11 will get rid of some of the redness. Should look better.
