Yes, demolition is has really progressed, with the site now 50% - 60%* rubble perhaps (*not a scientific or informed calculation). However, there may be delays to the demolition of at least one structure - the Charging Tower (which was still in-situ last Saturday connected to the VERY rickety, leaning and buckling hopper structure: Peregrine falcons are currently nesting in and/or around the Tower, also, there was also a colony of bats at the base of the tower with warning signs up to prevent entry due to their presence. Not sure if the bat colony is still there (doubtful) but at least one family of falcons definitely are.
Also last weekend, there were also two parties occurring in the fields either side of the Works. A bit surreal hearing the laughter of girls and Kanye West drifting over the air while exploring the site and dodging the active security patrols.
