catchup et al
Why should we?
It's all automatic.....
Many moons ago, enjoying the wonders of interline travel...
In the last seatrow of a Lufthansa B744 enroute FRA-NRT.
After enduring turbulence and cold over Siberia for a long time I stopped one of the "Gertrudes" passing by and asked if it would be possible to warm it up a little (everybody was wrapped in blankets as far forward as we could see).
She looked at me contemptously and uttered:
NEIN, ES IST AUTOMATISCH!!!! and strode away.
Now what is a poor pilot supposed to say to that? I went and scavenged the cabin for some more blankets
