2 circular objects flying formation after brief positioning next to each dark blackout night no lights 1 witness caribbean

It was a dark night on this Caribbean Island. The electricity had just gone out, total black out on the Island. I was lying with my girl friend outside on the hood of a car looking up at the twinkling starts when direcly overhead a bronze colored disc appeared clearly seen against the black sky. I watched it for a fews secs and then pointed up a said to her:  do you see that, she exclaimed in an excited voice - it is a space ship. The moment she spoke another similar object appeared, it has been flying direcly above or under the other, it shifted side-ways and then after oscilating a few times back and forth towards the other craft it was like it locked its trajectory next to the other one and both then flew on together till I could no follow them by eye anymore because of the blocking of the view by garden trees. I could not estimate their height or diameter. I do not consume alcohol, I do no use drugs I consider myself a regular person. This is not the only time I had a sighting but is is the only one together with a witness. Other sightings I will not list. Position of St. Maarten: 18.05 North, 63.4 West, direction of flight due west at constant speed. No lights visible on objects. No sounds.
