Cid they show the old daylight navigation charts.
Follow that railwaiy line!

One of my old acquaintances (1955) was an ex Qantas Navigator.
One day he was on a NSW intra state flight (after he had left Quantas but still had a commercial ticket). Asked to see the pilot and was let into the cabin. The pilot (no No2) was there with his feet up reading a book so my friend sat in the co-pilots chair. My mate said to him I did not know this plane had an auto pilot. The reply was that's right. Do you want to take the wheel for a while.
My mates next question was what is your course. Answer "See that railway there. Follow it for the next 100 miles"
