It’s an unfortunate reality of life that sometimes the best of intentions can have the most disastrous of results. That’s something which the city of Cleveland learned the hard way when they released a record-breaking 1.5 million balloons into the air way back in 1986.

Dubbed the “Cleveland Balloonfest”, the event was organized to raise money for charity as well as being “an attempt to break the world record for biggest simultaneous launch”, which was held by Disney at the time – broken the previous year for its 30th birthday.

To discover how the event ended up a disaster, check out the video below:

It took a staggering 2,5000 volunteers to inflate the balloons necessary for the record-breaking attempt.

So many balloons were inflated for it by United Way that they filled a structure the width of a city block in Cleveland’s Public Square.

Amazingly, the event was initially intended to involve the release of two million balloons, however, because of poor weather conditions, the final number was reduced and they were released earlier than planned at 1:50 pm on September 27.
