A spinning, glowing white UFO filmed in daytime by a local sky watcher this Saturday in Texas, according to the YouTube poster the object was morphing and changing shape from boomerang to a disc shape, but that might be a result of an extreme zoom in camera mode.
In my opinion, Crafts flying at such high altitudes such as this one, which appear not to perform any 'unearthly' air manoeuvres are immediate suspects to be identified as airplanes or maybe some kind of other classified government craft.
I will update this post if any thing new is updates on this sighting.
