This is the moment every engineer wishes they experienced once in their career.

The demolition of this 11-storey building in Dallas, Texas ALMOST went to plan. After the implosion, the building appears to be coming down when the concrete core of the building suddenly stops.

The building was left with a distinct lean but wouldn’t fall over. A 2.5 tonne wrecking ball was brought in but the building still remained standing.

It’s now being referred to as the Leaning Tower of Dallas and is attracting visitors. There are even calls for it to be retained as a landmark.

The former commercial building was constructed in 1971 and engineered by Thomas Taylor. Mr Taylor is undoubtedly having the smuggest moment of his career and was quoted saying “Nobody ever told me to make it easy to demolish”.

The demolition company says it may take weeks to bring the building down.
