Yes, the good old days of LFAT. When they had two runways (which were roughly at 90 degrees to one another) one was concrete and the other was tarmac. Even on my 6th or 7th visit there I had to really think hard about which was the runway in use. For some reason I always got confused between the two.
But I was relieved one day to realise I was not on my own when an English pilot made three attempts to approach the wrong runway and the controller was getting excited. In the end in desperation he told the pilot to land on the black runway.
