Weselfluren, a few years ago the company I was working for in Adelaide was looking at training ATCO's. They put quite a lot of work into research, and if successful, would have been great for the business.
It would have been a first in Oz. A company that trains both pilots and ATCO's.
Regrettably, it didn't get off the ground. Probably thanks to the government or a particular government department.
Good luck in your endeavours though.
