Groundhog,
What's going on here is similar to what goes on in other airport threads .... an over enthusiastic airport worker or few taking their work home with them whilst trying to preach that the world cannot survive without their little ol' regional airport.
The chopper operates the shortest reasonable distance between two or more suitable landing sites, namely Penzance, St. Mary's and/or Tresco ..... the former airfield of Royal Air Force St. Mawgan does not figure in this equation.
