You can watch a little bit of war from your nice living room - 30 seconds of what's going on in Syria - and when you've had enough, switch over to some celebrity programme. We live our life through screens and images in this way, and we don't know what is real or fake anymore. It doesn't matter.

This was 1978, when flying was still an occasion, a special grand event that took planning and care. I worked as a TWA flight attendant then.

Mostly, the passengers smiled back.
