I have seen some strange aircraft driving thru the saguaro national forest from oracle ( the biosphere) This mamajama was the size of a b52 bomber that just sank down into the mountains into what appeared to be nowhere, it just dissappeared. It was the weirdest( one of) things I have ever seen and I have seen some weirdness. That road thru the forest was in the middle of nowhere and one technically needed a truck, it was a rough ride. Near where the plane went down it was highly fenced( no visable buildings or structures), and secured it was military for sure. Another trip to Az was camping somewhere near tombstone on the border, had a close encounter with the eye in the sky for border patrol. That is another story
cool pics
see that all the time in my area too ( major metro area)
