Back about 20 or so years ago a commercial pilot did the same thing here in Central Kentucky. He thought he was landing in Lexington on a VFR approach and instead landed at the Frankfort General Aviation filed. The pilot realized his error when he noticed the runway was real short and had to really put on the binders and reverse thrust to stop it in time. The run way was so short that they had to unload most of the fuel to be able to fly it out. I believe they received a new career path also.
When I lived in Michigan, a North Central DC-3 scheduled for Howard City landed about 20 miles away at Big Rapids, instead.
Once aground, they realized they'd landed at the wrong airport. And there was no question of flying back out -- the runway was too short for even the takeoff run of a gooneybird.
They bussed the passengers out. Then took the wings off the DC-3 and removed it by truck.
Don't know what happened to the pilot and co-pilot...
