while in the navy me and another guy were military police on a navy ship standing watch on the midnight to seven shift. we were at the top level on the ship and my friend said look at that object.all at once a ufo looked to lose control headed toward the ocean; then out of nowhere a second ufo looked like it landed on top of the other one;after that it looked like some power source maybe electrical was bring the craft toward each other. the two crafts started to go up.as if toward the moon. the colors were a white/blue color;with roundish windows about four total maybe 23to35ft. wide and same long. the movement up was like slow motion.
