The plane had no problem at all, as the company said the pilot did not lose his orientation in any way, just the flight plan did not write Düsseldorf but Edinburgh!
Passengers on the plane were furious when they saw that they were flying to Edinburgh and not to Dusseldorf as their destination, and many were the ones who treated it with humor.
How did they get it? When the pilot welcomed them on their flight, he said the flight was heading for Edinburgh and, of course, it was a laugh. Some even made fun of it and they said … vote for what they want the plane to land!
