Update

Just to say that those tiny ant-like figures on the side of the building are abseiling workmen covering the damaged area with netting. Presumably this will stop any further metal cladding plates from swooping and soaring around like paper airplanes, instead making them drop straight down the side of the building. 

They are very difficult to see and I don´t know how to draw those red circles round them! One is about halfway down near the right edge and the other further down just below where the trees start. It gives you an idea of how large the building is.
