Hi probably out of my league here but been following the thread..this was so tragic and I'm like every one else just wondering how? From my limited experience ppl fixed wing .I have to ask the question if the chart provided as shown in the report shows the spot elevation as 282 at blckmo had the crew access to this prior or during the flight or just totally misread it?..it was there to be seen but maybe they had no access to it? Seems very strange ...also I think some else already mentioned it looks to me like it was intended only for the lighthouse to lighthouse route guide and It was never intended to be used outside the range that it covers
