Tezzer. They loaded the APBSS approach (well, flight plan really) which included BLKMO as it's first waypoint. They clearly did not know that BLKMO was Blackrock and that Blackrock was a 300ft tall lump of rock. Part of that was their fault for not reading the notes to the plate and the captions on the plate, but a large share of the issue rests with the operator for not making clear what this chart and approach was designed for, and more importantly what it was not designed for.
O'leary. What's becoming clear is that BLKMO didn't appear as a target (which they would have avoided), it most likely appeared as a caption for BLKMO (which they were aiming for) which happened to be obscuring the target.
