In flying we must be humble. Sometimes we must crawl before we walk,and walk before we run, and run before we fly.
The captain had NEVER been to the airport
The copilot had NEVER been to the airport at night.
THIS is the way you get into trouble.
IF you have an instrument approach available, or other methods like radar vectoring to final to an airport you have never been to USE THEM, ALL METHODS to verify the airport is the correct one.
I can imagine them playing who has the airport in sight first. Anyone ever hear of that one?
