Noticed an uncommon thing at the Amsterdam airport – between the takeoff strip and the airport, the plane runs over a tunnel which houses a highway! I could see cars coming towards the plane and then going under. It was quite shocking to see a civilian road running THROUGH an airport, when most of the airports keep people at a safe distance.
And when I pointed this out to a friend, he said that in Sacramento, when you are driving, you could see road signs that say – “Watch out for planes crossing”. That is WOW! It seems people have small planes parked in their driveways, taxy them to the nearest airfield and take off (to work)!!
