In a nice link (I hope) from my previous post about Religion, I'm writing this on board a Virgin Atlantic flight to the US. It has a rather superior seat-back entertainment system than the British Airways flight I last took. That had to be rebooted three times before it would work, which thankfully the Virgin one didn't suffer from. It has a rather more interesting map display, amongst which it tells me the direction of Mecca relative to my seat, and exactly how far away it is (currently 11292km)! Another thing BA could learn from Virgin: have lights in the loos that gradually get brighter, rather than suddenly coming on full when you lock the door. It makes quite a difference when all's dark in the cabin.
