thats not how ufos workI also think it looks like a balloon on a really, really long string. Alien spacecraft often appear to morph into somewhat different shapes and colors. This object does not glow or pulsate. Supposedly alien craft harness gravity waves for flight, giving them a jerky motion. This object just bobs up and down like a balloon until it abruptly drifts away, as if blown by a gust of wind. Sorry, I have to cast another "no" vote.
