Скачать или смотреть Construction Failure: roof suddenly collapsed under heavy snow.

In 2006, during a winter trade show in Poland, people were walking inside a massive exhibition hall — when the roof suddenly collapsed under heavy snow.

It wasn’t a small failure.
The entire roof came down.

65 people died. More than 140 were injured.

And here’s the shocking part:

Workers reported snow buildup.
They reported strange cracking sounds.
They reported leaks.

But the event continued — because canceling would “cost too much money.”

Later investigations found design issues, poor maintenance, and the simple truth:

Snow load was underestimated — and warnings were ignored.

Lesson?

Nature doesn’t care about schedules or budgets.
If a structure shows stress — you clear the building, then fix the problem.

Safety first. Always.
