I TRIED, BUT I CAN'T EXPLAIN IT

Tonight was a beautiful night, so I decided to drive up the hill to look at the stars. Unfortunately, the full moon created a lot of light pollution, so there weren't as many visible stars as I would have liked. I was leaning against my car when I noticed a star that seemed to be flickering differently than the others. I have watched the night sky several times and know that stars 'twinkle.' If you're interested in knowing why here is an explanation as to why. The article says that stars often 'twinkle' different colors. That is what initially drew my attention to this star. Most stars that I have observed might vary between different shades of yellow or blue; however, this star flashed (for lack of a better word) from blue to green to orange to red and back to blue. There was no pattern as to what colors flashed or when either.
The article also seems to explain the next thing that caught my eye-that stars appear to move. It does not explain the movement that I KNOW I saw. Once I decided to watch this 'star' more closely, I sat down in my car and stayed very still. There were power lines spanning across my field of vision, so I used them as a point of reference. It took a few moments for it to make any apparently outrageous motions. At first it only appeared to be moving across the sky at a steady pace, so I decided that it must be a satellite. Then it changed direction, ever so slightly at first then more dramatically. It did so many incredible maneuvers (that's what it looked like) that I started to eliminate options for what I was watching.

• It wasn't a satellite: satellites, although they can visibly move across the sky, tend to stay on a specific course (even when they're crashing into the ground),
• It was not a plane: no matter how it's flying, planes will move across the sky; unless it was some kind of Harrier or helicopter,
• In general, any aircraft can only stay in one spot for so long: I watched this thing for close to an hour; it moved a lot, but never any closer or farther away and it never moved great distances across the sky,
• The movements it made were too extreme to be a normal aircraft: I thought that perhaps it was someone learning to fly a helicopter (night experience, maybe), but it began to do more and more outlandish things,

So what kind of crazy movements did it make? It would accelerate quickly and stop immediately. Then change direction and do the same thing. A couple of times, it appeared to zig-zag three or four times. It did what I call a 'butterfly' turn. In a small airplane, it is when the craft starts low and flies steeply, turning at the top of the turn until is coming back down and then doing the same on the other side. Looking down, it might look like the plane is drawing a butterfly pattern; whereas, looking from the side it would look like a 'U'. That is the motion I saw. It did what looked like either a loop or a barrel roll, but it was too fast for a helicopter. And the craziest motion it made was what I would call leap-frogging or hopping. That is exactly the motion it made: hop, hop, hop. It did this several times. I've watched several helicopter videos, but saw nothing like this. During all this time, I maintained the power lines as a reference.
What, then, did I see? I don't know. I tried every logical explanation I could think of, and then it would do something even more radical. All I know is what I saw and it was not anything I can explain. I don't expect anyone to believe that I saw a UFO (I'm not even sure), but I would hope that those of you who know me would believe that I'm telling the truth, that I was not under the influence of anything, and you wouldn't try to be discouraging or condescending.
I know that what I saw, be it earthly or otherwise, was amazing and inexplicable and I am excited by that.
