When I got picked up at the Perth, Australia airport, my buddy told me about a couple of years ago when a Garuda 747 tried to land on Route 1 outside the airport......that's the highway leading in to the airport, not a runway.
Think about the reaction from the drivers on the ground. And what the pilot and co-pilot thought when they noticed those cars!
I flew Garuda once many years ago. Not a good rep at the time, and I could see why.
