After one of our pilots landed at the wrong airport ( I know of 3 such incidents during my employment ) our esteemed Manager threatened the next criminal with the sack. He then went and landed at USAF base Burtonwood instead of Manchester Ringway. He didn't sack himself.
One incident involved the crew landing at Cartierville (? name ?) GA airport just
north of the then Dorval Montreal international airport. A private pilot in a Cessna saw the landing and thought " The mighty XXXX airline can't be wrong" so he went and landed at Dorval !
