He got suspect on his wife having other guy behind his back. So he decided to use drone to track and record his wife action.

His comments "Used my drone to catch my wife meeting a guy at the local CVS. She had been getting called in early to work more often the past couple weeks, and then I got a call from someone telling me something was going on. I tried to follow her a couple times prior but both times she went to work, so I'm not sure if she was getting tipped off or I was just unlucky. So I took the drone up and that worked. Any questions you have ask in the comments. Thanks"
