I was riding from Durango Colorado to the Four Corners on Highway-160 over Memorial Day weekend. As we were riding in a rural area I noticed what I thought was a plane coming towards us for an emergency landing on the highway. I was looking around for a "Plan-B", when I realized it was a remote controlled plane. It turned 180 degrees and then hovered about 20 feet above the highway. As I rode under it, I realized it was a remote controlled Osprey with what appeared to be a camera and possbly a radar device. I did some searching on the Internet and learned that a remote controlled Osprey is currently unavailable, but that some remote aircraft company is working on one. So, my question, "has anyone heard if the Military, or some law enforcement agency is using such a craft for speed traps, drug smuggling enforcement, human smuggling checks, etc?". It was surreal.
