EGBK, Northampton (Sywell). The rather nice 1920/30's Art Deco Airport Hotel at Sywell Aerodrome. It has stood in for Croydon Airport, the original London Airport in a couple of episodes of the ITV drama Pirot. This is the airport side of the building, but is still fully open to the public.
Love the first photo! (Art Deco look) Thanks for sharing. Also appreciation the information provided.
