One time flying to Asia, I was wandering around and noticed that the curtain was pulled aside so I took a peek. The captain was sitting with his head leaning back like he was snoozing, the 1st officer was doing the flying, the Flight Engineer invited me in to chat (the FEs get lonely I think!). All those analog dials and gauges and meters! No computer screens back then. A fun and interesting aside in an otherwise boring flight.
The Queen of the Skies was truly a wonderful ship. On the times I was in business class on Pan Am trans-Pacific routes, the upper deck was a non-smoking business class area and it felt like we were in our own private plane. Those were also the days when the entrance to the flight deck was simply a black curtain!
