We fly construction site all the time for companies that want progress reports on a site. We flew a new project and all that is there is one port-a-potty in a grass field. I guess they have some work left to do.
The second month now and it has two port-a-potties and the grass is gone since they are scraping out the foundation area.
We never know if it is going to be a massive multistory building or a fast food place. It does not matter to us.
