FAST.....
We trashed that a few years ago... The terminal folks found that they were doing just as good as the machine if not better, and to make the machine to better ( as good as the controller ) it was going to take a lot more time and money. We ( the controllers ) told them to save the money and spend it elsewhere. The FAA did and FAST isn't really being used in the terminal environment. However, the other parts of CTAS are still alive and well and being put to very good use.
