Well, I certainly gave Haverfordwest aerodrome the benefit of a Hunter bluenote one day.... Called 'Right Initial' to Brawdy and set up for the usual 420 KIAS, 1000 ft join - then realised my error, tweaked back on the control column and just avoided their ATZ! Funny thing was it was the clearest day for months and no-one ever complained.
Then there was the incident in 1974 when a Gnat student was flying a PAR approach on an actual diversion to Shawbury. All was going fine until the instructor took control - and landed at Sleap.......
Countless approaches (and the odd landing) made at Dishforth instead of Leeming.
A VC10 pilot who made an interesting approach on Milltown instead of Kinloss - and then on the way back did the same thing at Fairford instead of Brize Norton!
Perhaps the best was the German who presented the RAF with its first Focke Wulf Fw 190 having mistaken the Bristol Channel for the English Channel - and only realised the mistake when, after chewing out an airman for failing to salute, the pilot was rather surprised to find himself looking down the barrel of a service revolver!
But none of these was by a commercial air transport aircraft flown by a professional airline crew!
