Here's an interesting theory: Fireworks shows are not only enjoyable family entertainment, they also provide cover for incoming aliens who can then sneak their aircraft into the night sky. At least that's the scenario one Swiss man is claiming he caught on camera during his town's annual fireworks celebration. Heinz Tobler's video, which he posted on YouTube, shows a multicolored disc or triangle-shaped aircraft hovering and then darting out of the way when an airplane gets close. Says Tobler's wife, "When we have fireworks, the UFO people think they can make a little trip without being seen."
One YouTube commenter was skeptical, writing, "Without including any reference points or scaling comparisons, it's very difficult to judge what a white blob on a black background is." Other commenters are more ready to believe. "Great capture, very authentic, and the object's movements are very interesting," wrote another.
