Dick,
I know I'm flogging a dead horse (sorry Woomera) but I'd be interested in your source(s) for the information on these incidents. Notwithstanding the free posting of information in these forums, you seem to be able to read the minds of the controllers, the pilots and the ATSB and Airservices investigators, sometimes before they've finished asking the questions much less written and released their reports.
Are you clairvoyent?
