Not picked the wrong airfield out before (or should I say yet). But while doing circuts for night training did turn final for the wrong runway at a certain northern airfield
many moons ago. ATC were very nice and calmly said you appear to be lined up for XX do you wish to take that runway! Managed to to correct myself rather quickly and bank over the 30 degrees for correct one. As both were lit and only 30 degree difference a small error but could have been a major incident, things like this we learn and NEVER forget!
