Interesting daytime video of a UFO activity in the sky above Boston, MA. This was filmed on 5th May 2014.
Witness report: Large bright glowing orb above cloud level and several small birdlike objects seem to be divebombing the glowing object as it flys away.
I went out for a hike at the Assabet River refuge in Stow, Mass. with my camera for wildlife photos when I happened to look up and saw a glowing ball of light quietly and quickly moving across the sky. I first thought maybe a meteor, then satellite or very high altitude balloon. It was solid white and disc-shaped continuously. I was surprised and amazed and decided to capture what I could on video. The object flew out of sight. On the video I later noticed smaller dark objects maneuvering nearby or around the orb. No idea what it was.
