I stumbled upon a crane accident in a place called Wateringen in the Netherlands. I actually found a couple of news reports about it. The big crane fell over and crashed through the second story of a newly built building. The crane operator was injured. The cause of the accident is unknown. It happened on 21st of April, 2005.

This is my first post, so hi there

/edit: I only have Dutch sources, the most detailed is this one.

It's the national website of the Dutch Firebrigades.

Rough translation of that page:

Crane accident in The Hague

21 april 2005

Just before 12 pm a crane fell on top of the upper level of a newly constructed building at the Laan van Wateringse Veld in The Hague. The crane operator was injured

The crane operator was working at the building when his crane fell on top of the upper floor and crashed through it. The operator also crashed with his control room on top of the building. The crane also hit a small building used by the people working at the building site. At the time of the accident that building was unoccupied.

The firebrigade first had to stabilize the crane in order to free the operator. He was taken to a hospital. The floor on which the crane is resting has been stabilized to prevent further damage.
