Very nice explanation and demonstration as to why we should not always trust data that is difficult to verify , and sometime sit is not easy to do.
the last sentence of the demonstration is essential in understanding incidents data , we knew it but worth repeating over and over.
This highlights another danger of simply using the number of reports filed as an indication of aircraft safety: not all incidents are the same........... the elevated number of incident reports stems from a very strong safety culture, not one of reduced safety. In this case, more incident reports are an indication of increased safety.
