Don't know anything about Moorfield Semley - before my time, but the dropping of these plans in 2002 seemed to be an instigator of the process to look for a professional partner to take the airport forward which led to Peel.
Newcastle produced Masterplans in 2003 and 2013

The White Paper The Future of Air Transport (Cm 6046, December 2003) states:
“Airport operators are recommended to maintain a master plan document detailing development proposals. An airport master plan does not have development plan status, but the level of detail contained within it is essential to inform the content of the Local Development Framework. We will expect airport operators to produce master plans or, where appropriate, to update existing master plans to take account of the conclusions on future
development set out in this White Paper.” (paragraphs 12.7, 12.8)
