orange pulsing light...black triangle flying low with bulge in the middle...green shooting start

***DATE IS AN APPROXIMATION***  I lived at the bottom of a hill in a neighborhood in So Burlington and at about 6pm I was walking to my friend's house at the top of the hill.  I noticed far off in the distance an orange light pulsating slowly in the distance.  I couldn't see it anymore as I walked up the hill, but when I got to the top of the hill I was facing north toward Burlington looking for it again when I looked directly above me.  
That's when i saw a black triangle with lights on each point and a bulge in the middle flying very low (maybe a couple hundred feet or less off the ground), slowly and silently toward Burlington.  It was almost as if I blacked out because by the time I actually 'woke up' or realized what I saw, the object was now a large bright white light in the sky still heading toward Burlington.  I watched it for another couple minutes as it was getting further away from me (closer to Burlington) still appearing as a bright white light.  
Then I noticed what were clearly planes (small red blinking lights) moving toward the light.   As the planes got closer the bright light got dimmer then faded out and disappeared.  I'm assuming it was gone because the planes seemed to circle the area.
Then I ran to my friend's house to tell her what I saw and we went up to the roof deck (which has a clear view of burlington and lake champlain) and we could see and hear that there were a lot of planes in the sky (maybe helicopters, too).  About 40 minutes later what appeared to be a low shooting star with a green trail behind it flew across the sky.  My friend didn't see it. I told her what i'd seen and traced the path across the sky with my finger.  When i was pointing out where it had disappeared, it lit up again and shot toward the ground in the form of the shooting star with the green trail.
I didn't see any mention in the news about it the next day and never heard anyone ever mention any phenomenon that day.  I've always wondered if anyone ever saw the same thing.
