I take issue with the paragraph included in the report as follows:
"On the morning of 22 February 2007, the pilot was observed by a flying instructor flying VH-ZGH into Hamilton Airport in weather assessed as being below the minimum visual metrological conditions(VMC)."
Whilst in theory this may be correct, who reported this information? An RA-Aus instructor, grade 3, grade 1, and IFR pilot, were they in the air at the time? etc etc etc.... I've flown in conditions that are VFR and had "instructors" tell the tower that its' not suitable for VFR, but yet the tower have taken this as gospel when it was clearly not correct.
I wonder if there were several of these reports that go towards the pilot's character, would the ATSB cut short the investigation and just say in essence "the guy is a 
-head, used to do this all the time, he probably just did it again and crashed?"
