Not exactly law enforcement, but similar...
Back in 2015, when flying a drone was like the Wild West, I had the urge to fly my Phantom 2 around the circumference of the 1.2-km diameter Meteor Crater in Arizona. I researched the best location to launch from such that I could conduct this operation without being bothered and without bothering anyone else. Using Google Maps I found a remote intersection on a public dirt road. I rented a car and trekked out there for some flights.
My first sortie was as spectacular as it was uneventful. Made it to the crater and partially around the rim. No flight issues.
While changing the battery, I noticed a white pickup truck heading toward me on the empty dirt road. It was Meteor Crater security. He stopped and confronted me. He told me to stop what I was doing and leave the area. I don't think he knew exactly what I was doing, he just didn't want me there. I said I was on public land and had a right to be where I was. After a few minutes of back and forth he squawked something into his radio and left.
I started my 2nd sortie. A few minutes later, he drives back-- this time with his boss in a blue SUV. They both get out and confront me now. At first things are tense. They told me that the road is public but if my drone falls anywhere to the left of the road I would be trespassing if I went to recover it. They also said the airspace above the crater was owned by Meteor Crater Inc.
At this point I start to bring the
P2 back, with GoPro filming the scene in case something happened.
But things cooled off quickly when I told them I had just visited the Meteor Crater and took the tour (paid admission) and was not just a troublemaker. They then told me that they've had problems with people parking here and hiking up to the rim of the crater, drinking beer and such. I explained what I was doing and that the video of the crater would end up on YouTube and could possibly lead to more business for the attraction. That seemed to satisfy them and they left on peaceful terms. Not wanting any more attention, I left shortly after.
Here's a snapshot of the two security folks watching what I'm doing:
Here's the final video of the Crater. BTW, I highly recommend visiting Meteor Crater if you get a chance. Just leave your Mavic in the car.
