I thought I´d share this interesting piece of information with you:
I just got my hands on a Lufthansa Super Connie postcard, and they state on the back what the crew looked like:
1 first officer
1 second officer
2 flight engineers
1 communications officer
Sure must have been crowded up front. Oh, and the cabin crew consisted of only three steward(esse)s - so, 10 total, of which seven are in the cockpit.
