I was on watch on the fantail on a uss warship while import in. I looked up and seen three Green objects just hovering. I started watching as it was my job. They started to move to the right slowly and then stop. Then they started to move again to the right. As I am watching them move to the right they just took off straight up into the stars, then into the blackness of space. I could not believe what I was seeing. I knew there were no aircraft on earth that can move that fast. Just like Star Trek Warp speed. I just got into Navy and didn't want them to think I was crazy. I didn't tell anyone until a few years later. It's kind of messed up to see!! Not supposed to see that stuff.
