Captain Sand Dune,
The local politicians down in Sale have been talking this up like it's already theirs. They have been spruiking a lot of garbage about how the weather in Sale is superior to Tamworth's. You can do a direct comparison on the BOM website , and it proves Tamworth is less cloudier, less windier and less rainier in every single month.
The ESL airspace and ILS will become totally maxed. How will ATC handle all the extra traffic? I've heard that BFTS is the busiest unit in the RAAF.
I think those companies are trying to get their foot in the door at WSL on the assumption that 5428 will be setting up at ESL. A very dangerous (and expensive) assumption, because there are no guarantees about what 5428 will look like and where it will end up.
East Sale - Very good for CFS, but totally inappropriate for BFTS.
