I think the title “Lands at wrong airport” is a bit misleading. The flight plan was to Edinburgh, the pilots intended to fly to Edinburgh and they did fly to and land at Edinburgh. So comparisons to Ryanair landing at the wrong airport by mistake are not appropriate and saying they should have queried a Northern SID is not a valid comment because all departures to EDI have a Northern SID so that is what the flight crew would have expected. Also no fuel anxieties because they would have had the fuel for their planned flight to EDI. There has clearly been a big cock up as to why the flight plan was to the wrong airport and my thoughts echo a lot of the other comments above.
