Thank you for the information and pictures. I note that the first graphic displays a circle at the top containing a reference to MSA information being displayed on Page 2. That is extremely relevant to earlier posts where many posters were absolutely insistent that all approach plates contained all relevant information on a single page. The information referring to the height of Black Rock Lighthouse was also apparently contained on a second page according to information contained in the preliminary report.
That certainly helps develop my mental picture of what could have happened. It will be interesting to see if this forms a significant part of the final investigation report.
