Two bright objects in the night sky in Cape Canaveral, FL.

It was a warm summer night in Cape Canaveral, FL.  No moon as I recall, the sky was very black and the stars shone brightly.  My fiancé at the time (now husband of 22 years) and I were stargazing on the beach off of Lincoln St. on the boardwalk.  To the left of us was Kennedy Space Center, to the right of us The Pier.
 I would also like to note that there were no launches that night.  Since I grew up in Cape Canaveral this I would have remembered along with seeing these objects.
 Suddenly out of no where there appeared a very bright light that seemed to change in colors.  The object hovered above the ocean just to the right of the Space Center.  It would move in and outward, then it would appear to rise in the sky and drop suddenly and stop.  It moved in directions that I have never witnessed before!  It made no sound that we could hear, only the oceans waves were heard.  A second object then appeared and both of these moved around almost as if following each other, then at other times they would be doing different things.  One would be moving towards the beach and one would be rising up or down above the ocean.  We both have never seen any aircraft move so effortlessly in a manner that these objects did.
 My husband and I both asked each other if we were both witnessing the same thing, wondering if we had lost our minds!  We watched the objects for probably a good 15 minutes doing it’s dance in the sky.  Suddenly the first one or lead object seemed to move in quickly at us (but still kept a distance away), like it knew we were watching it, then backed off to where it was then in a flash both of them were gone leaving what seemed to be a streak in the dark sky where they had moved so quickly out of our site. Not a trail, but a streak that vanished in a second!  Over the years we have told many of our friends of our experience, but never thought to report the incident until I ran across your site.  I have looked to see if others perhaps saw these objects that night, but did not find any.  Since I can not remember the exact date I will have to estimate it.  I know that this happened in 84, it was in the summer months and it was before we married in 1985.  Sorry I wish I would have wrote now the date and kept it somewhere.
Witness indicates that the date of the sighting is approximate.  PD
