D 129 says the pax will want to see someone up front
747Focal says 2 pilots are there
How do they know?
The doors are locked, the pax don't get to see who's behind the door.
On my last trip just before push back a voice declaring himself "the Captain" announced our flight time would be 9 hours and 36 minutes and there would be a smooth flight all the way.
Some 9 hours and a bit later another voice declaring himself "the First Officer", stated we were starting our descent and it was raining at our destination.
I do wonder if the "Captain" is still in Jo'burg, and the "First Officer" never left Kuala Lumpur.
