Flight 447 A Cultural Revolution Flight 447 This Sunday, the story of Flight 447. It has been called the "Titanic of air disasters". A passenger aircraft so advanced that the chance of it falling out of the sky is unthinkable. But on a stormy June night in 2009 that's just what happened to an Air France A330. Its terrifying descent into the Atlantic Ocean took just four minutes. For three years, what happened inside the cockpit remained a mystery. But as you'll see now, the black box tapes have revealed a shocking and scary scenario of how quickly and easily a high tech passenger plane can crash. Reporter: Karl Stefanovic Producer: Gareth Harvey A Cultural Revolution There's an old Chinese proverb that says "women hold up half the sky". And in China today, there are plenty of tough, independent and very wealthy women who seem to prove it. Half of the world's female billionaires come from China. Not surprisingly, a lot of young women would like to follow in their footsteps. And plenty of them are Chinese-Australians, heading back to the land of their forebears. It's a kind of reverse migration and when you see the dizzying fortunes and opportunities in China today, well, no wonder there's a new gold rush on.
