I hope we are not going to make this into an age thing
I remember Harrison Ford flying into a small UK airport a long time ago he is a true aviation enthusiast
Making a mistake like that is not unique not even to airlines
I remember only too well the Ryan air mistake at Londonderry where a 737 approached and landed on a nearby disused airport
The PAX had to be bussed out but the disused airport obviously wasn't identified as such by either the professional Captain or his FO
In a basic aircraft like the Husky it is a pure visual aircraft and hence much more likely that a visual mistake was made
I also ask where were ATC in this ?
Surely they should have told him to Go around as he was landing on a taxiway?
