This was at that time commonly overflown at quite low altitude by inbound traffic from Scotland/Ireland to London City, Scot Airways Dorniers etc, from which I got good views over time of the demolition, raw earth, and then rebuilding. There wasn't a radio point there or anything, but it was just on a line heading to transit overhead Lambourne VOR. Routing has changed now to a much wider loop, out beyond Southend, and often (bizarrely, coming from such a direction) with a view of the French coast.
