It was a pretty crummy day today but I wanted to get my P2 and GoPro up for some flying time. Between rain showers I went out in front and launched in the direction of my house. There is a pretty good sized wooded area and retention ponds between my house and the next neighborhood. I sent the P2 up to probably 200-300 feet, well below the cloud cover and was taking still photos. Then I heard the engine of a small plane. The plane (a small Cessna) came over our neighborhood probably around 600 feet. Easily at an altitude my P2 could achieve. I had very little warning before I was aware he was nearby. I don't live near an airport (big or small) and rarely see aircraft that low unless the Sheriff or local news choppers are on the hunt. There are a lot of videos out there of people sending their Phantoms way up and doing FPV flights well beyond visual range. Whether or not this plane should have been where he was at that altitude is really beside the point. I think we really need to be careful where we fly and how high we go. Things happen very quickly up there.
