I saw a ufo flap Dec. of 1993

In the latter part of 1993 I had a concern in Ft.Lauderdale that required me to drive alot on Interstate I-95. As I was headed home going north on 95 between 1:30 and 2:00 am I saw "something" that was traveling at an extremly fast clip leaving a florecent green trail in the shape of a triangle and there was this orangish white light object traveling in a tight corkscrew path through the bottom middle of the triangle making a lazy "J" that was the color of a modern day streetlamp. Each side of the triangle was, at best guess, 15 to 20 miles long, and it had to have been 25 to 50 miles away from where I was. About 3 days later I was traveling down the same hwy at about the same time in the same direction when I saw what looked like a propeller from a helecopter(again florecent green)whizzing by me on my right(West)side with two more orange-white sentinals on either side of the "propeller". And about five days after that, I was getting out of my car in my apartment driveway when I saw a single orange-white sentinal light make another lazy "J" into the nightsky and disappear.
