"You yell UFO, everybody says, "Huh? What?" You yell Sky Shark, we've got a panic on our hands on the Fourth of July."
Last month, video shot of a purported UFO by Brazilian teenagers caused a bit of a stir in skeptical and UFO-friendly circles alike. The footage of a shiny, spherical object cruising through a beautiful, blue sky certainly looked like the real thing, but as it turned out, the "UFO" had an Earthly origin - albeit a highly amusing one: It was a remote-controlled helium shark manufactured under the name "Air Swimmers".
After receiving its due 15 minutes of fame via quick-on-the-trigger local media, the flying fish was revealed to be the property of a neighbor.
