If you mean the wooden fence one alongside the heliport ? It went up without any consultation with the resident helicopter operator at all , who I believe were annoyed at the time because they had no objections to kids/families/spotters etc watching their coming and goings - and always managed a wave from the crews - good
PR especially for the offshore passenger meeters/greeters watching their partners arrive/depart , fence originally installed by the airport operator supposedly to reduce noise for the local residents in the area
All the decent viewing areas are disappearing fast , watch that fence around the front of Blackpool Air Centre entrance going up , another one installed by the airport
