This is one of my ‘favourites’ of the collapse videos as I think it has the least smoke to hide the progress. It shows the path of the antenna and its delay within the collapse front, the change in dust pattern as the upper block reaches the upper mechanical floor, the remains of the core columns immediately below mechanical floor level and the sheer weight of the dust and its speed of descent.
Try as I might, I struggle to attach any control to it, less so to even think of the word ‘obvious’.
I can see falling, tumbling and toppling of substantial chunks of the primary structure and fluttering of cladding etc. but no ejection other than for smoke and dust.
