It's happened before and will happen again. As long as the landing itself was routine then a case of mistaken identity. Some retraining for the pilots and things will be back to normal.
It is interesting to note that they were intending to land on rwy 14 at the larger airport but landed on rwy 12 at the smaller. I wonder whether the smaller runway had numbers painted on the threshold (as some smaller runways do not).
