Myself and another Marine were walking from our hangar, out to the flight line. We both had our tool bags and were talking while walking out there, due to the length of time it took to walk out to our helicopter. I glanced up to my left, and saw a small, shiny, metallic craft, flying from left to right, way up in the northern sky. It was a clear day, so it immediately stood out like a sore thumb, and I stopped to look closer. It seemed quite a long ways up, but it was a bright sun shining day and the sun must have been reflecting off of it. As I was looking at it, it stopped abruptly and another craft just like it, came into view. Same flight path, but a little higher elevation and not quite as far as the first one. I turned to my buddy, and asked him if he saw that, as I was pointing towards them? He said yeah, he saw them too. After a few minutes observing them hovering in the same spots, they both ascended straight up, as quickly as they came into view. We looked at each other, wondering what we just saw. I honestly don't remember sharing any of this experience with anyone else and I'm not sure my buddy did either. However, I did see him several years later and asked him if he still remembered that, and he did. I probably didn't, because I thought the guys in our shop might give us a hard time about it. I'm not sure how long Mufon has been around, but I was watching a show recently, and decided to share my experience. I've never had any other experiences, that I can remember. However, I have always been curious about the possibility of others having similar experiences.
