At this stage everyone's guess is as good as mine. I would caution about getting too excited about a resumption of any meaningful aviation activity. The fact that the Flight Sheds area is the prime focus of attention for the film studios, does suggest that aviation is not top of the list of priorities.
Some of the proposals I have seen have the runway laid out as a main road into the site, linking up with the new by-pass link. Likewise rumours of the likes of DHL etc suggest to me road freight depots.
As it was on the last day of BAE airfield operations, see
here.
As it was over many decades, wallow in nostalgia
here.
Hopefully there will be a favourable outcome for the resumption of some form of flying activities, but given the limited one sided press stories we have been reading, I will not be expecting much at this stage.
