From the control tower I have seen so many scheduled arrivals make a 8alls up of a visual approach. e.g.
A 747 bouncing after touch-down after a staggeringly incompetent hand flown final approach path.
Captains’ requesting orbits at 4NM final after getting the height wrong, and then treating 200+ passengers to a guided tour of the undershoot area.
Other, equally big boys, lining up on the parallel taxiway and then enquiring in a haughty voice " xxxx Tower are you landing on 34L or 34R this morning”, when there is patently only one runway.
Traffic landing so deep into the runway that they are cordially invited back to the spot landing competition at the weekend.
The list is endless so it’s no surprise to an air traffic controller that this sort of incident can manifest itself. Thank goodness it happened in Denmark where they will investigate the “system” and not the hapless controller/pilot.
