While sitting on my couch watching "Brain Games" on NatGeo TV, my wife yelled out "What the heck is that" and I turned to see a red, pulsating object drifting upward about 100 feet, then change direction and head along an altered vector in a steady, linear fashion. I thought for sure it was something goofy a neighbor was doing but since there was a story posted earlier today about UFO sightings "on both side of the Atlantic" I figured I'd start rolling with my HTC G2 camera. The video quality is as you would expect, somewhat crappy, but as I was capturing this flying/drifting object I then stared hard at it to see if it was anything I could decipher. But honestly, I have no idea what the heck it was. It went behind a tree and never came into view on the other side, but I saw neighbors on their balconies pointing and gawking at it too.

So, for what it's worth, here's the video I managed to grab of it. The closest explanation I can offer would be something along the lines of "a box kite with a bright and pulsating light bulb inside it, traveling in a very steady and laser-straight direction without wavering or fluctuation."

It will be fun to wonder what this object could have been, but I feel as if I'll never know?
