As an April Fool’s joke, two men decided to show how easy it is to fake UFOs, and how easily people could be fooled. They tied lit road flares to helium balloons and released them. No one was hurt, but they were charged with creating a disturbance due to the flood of 911 calls received, and the fact that the distraction could have caused a traffic accident.
When you click the link, the photos taken of the “UFOs” road flare ballons in the sky look remarkably like many recent highly publicized UFO photos/videos. You know those videos where people exclaim “Oh, the light just hovered forever, then miraculously disappeared - It must have jumped away using some kind of hyper-drive!” Road flare tied to a balloon hovers around for a long time, then goes out. LOL.
I got kind of a chuckle out of the prank. However, I can see how it would be dangerous - someone could run off the road or have an accident, and it took up a lot of police time and tied up the emergency services line. But I don’t think the pranksters meant any harm.
