On Sept. 27, 1986, the citizens of Cleveland, Ohio, looked up into the sky and watched as the sun and clouds were blotted out by more than a million helium party balloons released during a fundraising stunt put on by the United Way. The balloons were filled by thousands of volunteers who placed them all into a massive enclosing net. At 1:50 p.m., they released the balloons on the news of an approaching rain storm. The organizers expected the balloons to fly high and far away into the sky, but watched instead as the balloons collided with a cold front and sank back down to the ground.

Parts of the city were covered with the sea of downed balloons. A nearby airport had to shut down one of their runways for a half hour after it was covered by balloons. Cars crashed into each other and the Coast Guard was hindered in an operation to save two fisherman by the balloons floating on the water. Finding a missing person in the water is hard enough without having to deal a thousand head-shaped objects in the same space. Sadly, the fishermen died.

The United Way was hit by millions of dollars in lawsuits and the city had to deal with cleaning up the 1.4 million balloons.
