I understand that in the UK an airline aircraft cannot operate unless there is either a tower or a Certified Air/Ground Operator at the airport.
Considering the geography and dimensions of the UK in the context of the amount of airline air traffic at any given time, I think that Dick is yet again comparing apples with oranges. This debate should be about the Australian situation, the geography, the dimensions and the mix of traffic that occurs away from the J-curve. It's a different world.
