Re: Cabin crew
I've been on a few flights with similar experiences (drinks down suits, etc.) but on one of the calmer flights I flew there was a little period of bumpiness where the crew were looking absolutely fine, as were (most of) the passengers. However, about 5 minutes after the bumps the lady looking after my section suddenly looked a little drained and took a break on the jump seat in front of me (exit row, first through US immigration...). She confessed to me quietly that she hates and fears turbulence, but hides it as best she can due to reflected fear...
Lesson to learn: The crew are humans with the same insecurities and fears as the rest of us. Sure, they face it more often but that doesn't necessarily make it any easier on them.
Since then I've not looked at them. Since quite a lot of turbulence that some would find uncomfortable is no worse than shutting your eyes as a passenger in a car going over bumpy road, I now just shut my eyes and imagine just that...
