I was out flying and discovered a new building being erected close to my house. My company makes the accessories to erect buildings and the panels etc. Low and behold our products were in this building being erected. I flew inside this huge facility being built and took several photos and shared them at work the following Monday. Now everyone at work wants me to submit them for the best picture contest which is nationwide. If I win or rank I win cash. Would this be considered illegal by the FAA?
