HONG KONG — What is it about aircraft that can induce a serious bout of megalomania?

Richard Nixon, when he wanted to get away from the presidential office and imagine that he was in control of his own destiny, let alone that of the United States or the world, would take Air Force One for a spin to get a sense of perspective and see the world from an appropriate distance.

But is it not worrying when supposedly stone-sober airline bosses, ensconced in their offices with computers, spread sheets, and telephones telling of recalcitrant staff and stroppy passengers, start indulging in escapism and dreaming of their ideal world?
