That was not a good video. The person running the camera kept moving the camera around and zooming in and out. It looked like it could have been a blimp covered with lights. The video was not clearly defined just like every other UFO video.
I'm surprised I haven't seen more "I Don't Want to Believe"* types here suggest that people are being fooled by very popular, affordable new electric RC helicopters. They're amazingly agile in the air, able to hover and stop and do all kinds of maneuvers, and are silent.
Of course, there's a reason electric RC helicopters couldn't be the explanation of any dramatic night sightings of silent craft (daytime, maybe, but not night sightings). The helicopter might be able to ferry the weight of the lights, but never the weight of the batteries to power them.
*"I Don't Want to Believe" I hope and pray that we all live to old, old age and die contentedly never knowing the truth about UFOs, instead still having the silly arguments like we have here on blessed FR happily into our final days many decades from now. I don't want to believe they're out there ... but then, there's a lot of bad stuff I don't want to believe. However, I'd rather be prepared mentally than ambushed, and I think that when these things/critters make themselves officially known to us, it will be the beginning of the darkest days we humans have seen. I place my faith in Christ and the Lord God Almighty.
