They don't need an image recognition system... Story time - My first tour in the five-sided wind tunnel was 2005-2006. I was at Quantico for school before that so had three years in the Northern Va area. I was always into RC airplanes and flew at a nice grass strip on the west side of town off Route 50. I was out there was weekday afternoon and there was only one other person out there with me. When I pulled up I noticed he was sitting in a chair and wearing some kind of goggles. Next to him was an antenna system mounted on a tripod. I watch him fly for a bit and noticed he was not looking at his airplane. When he landed I walked over and we had a chat, he was testing a home built system that pushed video from a camera in the plane to his goggles. We talked for a while and told me he posted a few videos of his set up and some of the flying on Youtube. He then gave me his channel on a card. A few days later I looked at his channel and while watching a video noticed an airliner go through his frame...a cold chill ran down my spine when I saw the airliner. The field was a few miles from Dulles and almost all of his videos caught an airliner in the frame making an approach to the airport. I immediately put that together with another project I was working in a small strategy cell I was assigned to in the Pentagon. In short, just the previous two years prior a group of hobbyists flew an RC airplane autonomously across the Atlantic Ocean. I pitched the project to my boss and got some seed money. Long story short I proved an amateur could build an autonomous airplane that could lift a 20 warehead/payload, fly with a GPS auto pilot and hit a target at range or via FPV for under $1000.00. This was 2005...I wrote it up and tried to run it through the system only to be laughed at and ignored.
