Several years ago, when taxiing out at Linate, we were confronted by an Alitalia making a very stable approach to the Taxiway! Nice clear day, from our position on the ground. All of our lights on, and a very busy ATC frequency, so we couldn't get a word in.
Fortunately, they realised their mistake, and made a very obvious turn to the correct runway at what appeared to be fairly low height (we guessed about 300feet) and all ended happily.
It happens.
Many things that happen in aviation can be looked at from a number of perspectives. But once it's happened, one most important thing is to understand the 'why', to avoid the repeat as best we can.
I'm sure that since this event, a great many of us have been reviewing in greater detail, the presence and orientation of the taxiway at PFO. I'm sure also that there are some who have dismissed the event as something that cannot possibly happen to them.
We can discuss at great length the 'poor choice' of having the runway between the taxiway and the apron, but worldwide, airports have a lot of unique features, and repeatable features. Parallel runways, long parallel taxiways, designated runways that serve as taxiways (DLM 01L is Taxiway F, most of the time). PAPIs on the left/right/both sides. Side step procedures that get thrown at you unsuspecting (unless you briefed it). Obstacles on the approach. Approach lights, unless they are turned off.
I would like to say it will never happen to me. But I am sure I am NOT infallible.
Of the best people that I have flown with, all are cognisant of their ability to make a mistake.
Of the worst people that I have flown with, all are convinced that they are the best, incapable of error, and the mistake is by someone else. (this latter group seem to encounter more problems/incidents, strangely)
