Seems that Biggin Hill are rubbing their hands with glee and anticipation over this and not surprisingly. If RAF Northolt were to be outlawed for bizjet use, they would obviously hope to reap some of the benefit from increased movements.
Problem with BH is that the road links to/from London are poor. The recently advertised helicopter shuttle from BH to and from London Heliport Battersea, (a snip at £2300 plus taxes), might appeal to some. But if Battersea, a wholly private landing place, were to close, what then?
Why not open up a new heliport at London City? Is it time to revisit the long time ban on helicopters operating from there?
