While running across the vast lands of google earth I stumbled across an airport. I was going to just look at it really quickly until I saw these white lines next to the centerline (see image below). I then started to wonder what these lines could possibly be. I then quickly got onto our poor quality tablets and quickly searched every possible article I could find. From exact measurements about each taxiway lines to how many angles they are supposed to face. I even read about a wheel chair man getting his wheel chair destroyed by American Airlines and being curious about why he wasn't mad. But no results were shown. After hours of research no luck appeared and to this point I still have no idea why these white lines in this white box exists. If you want to help me figure out this very big issue of mine please tell me in this thread.
