In the news

Out of control may just be that the pilot was unaware of the crane due to not seeing it while trying to maneuver around the building.

The tail is currently resting on top of the building I think?

That means the fuselage struck the crane with enough force to shear a huge portion of it off in the impact. It didn't take a glancing blow from the crane it full on hit it.

Helithing was going south - ish, and the crane was pointing north-ish last night. I iz clearly technical. Something apparently landed on the roof of St George's wharf, but some of the tail of the helicopter is on the roof of those data yellow storage buildings
