NAM's already had the first visitors who have given up trying to get into the Waddington Airshow; apparently there're also travel issues around Newark (A1/A46/A17 junction & in Newark itself), which has caused some passenger delays for the Airshow Helicopter Shuttles that are operating from NAM (people stuck in traffic were late arriving etc.), however everyone has now been safely flown out to Waddington.
NAM is on extended opening from 0800 hours to 1900 hours today and tomorrow.
RAF Waddington International Airshow may not have tickets on the gate.
Might help someone
