Anyone see that and wonder how those long international flights that track the sun would allow passengers to sleep?

I thought this - then remembered the A380's lighting systems that (in theory) help passengers get less jetlagged. Similar to F.lux [ http://stereopsis.com/flux/ ] for display color temperature, just on a bigger scale.

That would be the in-flight entertainment.
