Richard Branson's April Fools Day UFO

Designed to be an elaborate April Fool's Day stunt, Richard Branson and Don Cameron brought London to a stand still with a special shaped UFO hot air balloon.

Built by Cameron Balloons Limited in Bristol, using the code name "Project Wedgewood", only a handful of people new about the project. The balloon took off in complete darkness with various strobe lights flashing and flew over the M25 - it landed safely, just as the sun was rising. The stunt created massive media coverage for Virgin Galactic Airways!
