"...but the asiana crew made the costliest in terms of death, hundreds of injuries, and property"
The 747 wrong airport landing did not cost as much as the Asiana accident but luck was on their side.
The 747 crew were lucky they didnt blast into the WRONG traffic pattern and collide with another aircraft or run off the SHORT runway into houses.
Dont judge the level of oversight based upon the end result alone.
They screwed up big time and it could have been a lot worse.
