Good idea, would not work for the GNAA, Cleveland police are losing their aircraft
Considering that the proposed new GNAA centre would be 50m across the road from the Cleveland & Durham Police Tactical Training Centre, and only 2 miles down the road from their current location at the airport (good for crew travel times remaining the same), something might have worked out.
However with only a single figure number of weeks to go before NPAS Tees_Valley closes, despite Teeside being central to the region and only c10mins flying time to Newcastle, it's all too late.
Having said that, the linked report in the 'op' mentions the GNAA base at Newcastle International Airport will continue to be “integral” to its future plans.
