Strangely Brown and Marlon chose a more adventurous route into Cell 4 by climbing into the air main and exiting it via a convenient ladder fixed to the side of the cell wall. This was only possible as the Sahara set-designers removed the section of pipe from the mouth of Cell 4 to the wall; and had also removed a section outside the building. (This was to allow Matthew McConaughey and Penélope Cruz to climb into the pipe for the first reveal of Cell 4 in Sahara.) Whilst this allowed a brief interlude for us to appreciate being in exactly the same space as Penélope Cruz we noticed that as the air main angled upwards for its turn over Weir Road it was fitted with internal ladder struts.

By now Tom had returned from his solitude in Cell 3 and everyone was climbing up into the elevated section of the pipe. Tom took the lead, disappearing around a bend in the pipe, revelling in the acoustics and whooping in delight. Marlon joined in the now cacophonous calls, setting up long exposures and capturing a bizarre blurred shot which matched the soundscape. Alex and Tom were caught in various multiple poses, bouncing along the featureless pipe, lit by the sweeping light of multiple torches.

"Is this pipe actually moving?"

It had become apparent that five people were starting to cause the pipe to bounce and sway a little. During the working life of Pyestock, it just had to support the air stream and little else. Perhaps five urban explorers running up and down with torches was just a little too much for the pipe’s supports. And it must’ve been an odd sight outside with the pipe swaying in the air and miscellaneous whoops, calls and footfalls echoing around the quiet site.
