It's interesting, not even a month ago this forum was debating single pilot cockpits being the wave of the future.

Now we have this-

"Lufthansa, together with other German airlines, has announced the immediate introduction of new rules for the cockpit. It will now be a requirement for there to be two authorized people in the cockpit at all times."

My guess is the future will have to be no humans in the cockpit or at least two, but never one.
