An immense animal flock of 1.5 million air balloons took off from the land of Cleveland in 1986, forming an uncontrollable cloud of magnificence proportions. The show, known as Balloonfest '86, was organized by the United Way to break the world record for biggest simultaneous launch.
The liberation of the 'creatures' grew as a giant tree and started drifting in the azure, filling the sky like a surreal painting of Magritte. The result was incredibly disarming from any point of view, after the charming it was pure perturbation.
When the balloons got wild and met a real storm that led them back to the city, they caused severe consequences and damages. Helicopters could not fly and two people died in the water because their heads were completely camouflaged by hundreds of floating balls.
When the danger comes out of a clear blue sky... Likely the balloons were biodegradable!
