No excuse whatsoever for landing at the wrong airport. Errors such as this happen when there is breakdown of SOPs and CRM. I've never seen an FCOM that had a statemen to the effect that if a visual approach is to be accomplished then naviads when available shall be tuned and identified as a backup and confirmation.
I remember years back a CAL with an FMS landed at the wrong airport at Corpus Christi in CAVOK conditions. The excuses and justifications were just beyond belief.
Yes... Jeppy needs to insert notes about airports that may be confused with intended airports of landing to help preclude such incidences.
