There have been many incidents involving planes landing at the wrong airport. A friend of mine was Flight Loadmaster on a Dan Air 748 that was supposed to be going to Belfast Aldergrove. Unfortunately the captain could not be dissuaded from landing at a disused GA field near-by. The first officer stood up and was shouting into the CVR area mic, "I dissassociate myself from this flight! I have nothing more to do with it!" Even after they landed, the captain refused to believe he had made a mistake, abusing the tower for not sending a Follow Me truck out to meet them. The tower's very sensible defence was that they hadn't landed yet. "Yes we have, we're on turnoff three, taxiway alpha [or whatever]!" "...Um, no you're not."
A BEA flight to Paris was lined up for landing at the wrong field and again, the first officer had spotted the mistake. Unfortunately this was the fifties and the captain did not take to the first officer's remarks. After they landed, the captain realised his mistake and told the first officer to radio ahead to Le Bourget and tell them they would be late. "I already did, sir." "When?!" "When we were on finals. Sir." Reminds me of another domineering BEA captain annecdote-ette, they were very close to the ground, houses getting very big etc, and the captain had still not asked for the gear to be lowered. Unable to take the suspense any longer, the first officer (in contravention of all known cockpit etiquette of the day) piped up and enquired if the captain might like the gear. "I will ask for the gear when I am good and ready!" A pause of approx 0.001 secs. "GEAR DOWN!"
The worst illegal landing incident I heard of in recent times was a British Island Airways BAC111 that landed on the parallel taxiway in bad visibility at Gatwick. The only thing that avoided a potential five-aircraft pile-up was the fact that the taxiiway was empty at the time. A Delta TriStar was lined up to land at Northolt, a tiny WW2 field in West London, when it was supposed to be landing at Gatwick, 60 miles away. The controller asked the flight as politely as possible if they "knew what they were doing." The most embarrassing incident would have to be the NW DC10 that was lined up to land at Brussels (Belgium) when it was supposed to be landing at Amsterdam. Every single passenger knew cos they were watching the entire debacle unfold on the moving map screens. That's like flying from LA to NY and seeing the CN Tower (Toronto) flash past at eye level as you begin the final approach. Oops.
