You're not living up to your name O&W.
The chart doesn't show Blackrock at 282'. It shows a waypoint called BLKMO with a caption next to it of 282 with no clue as to its relevance. Is it waypoint 282 in the operators manual ? Is it the depth of the sea at this point ? Is it the QDM from some unspecified navaid on the mainland ?
The island would indeed have been visible on radar and on the EO/IR display if that was available in the cockpit, and for that mistake and the few seconds pause whilst they assimilated the rear crew's input this crew paid with their lives.
However the people that put them in this situation by promulgating a thoroughly misleading chart, and the people that validated a flawed terrain database have yet to be held accountable for their role in this accident. And I'm willing to bet that their punishment will be less severe.
