1Fatal Flaw The Robinson R44 is one of the most popular helicopters in Australia. It's commonly used by small business, tourism operators and in regional Australia. For nearly 20 years it's been allowed to fly, despite mounting proof it's a death trap. It has a faulty fuel tank that can explode on impact - turning minor and survivable accidents into deadly infernos. In a special two year investigation, 60 Minutes has uncovered dozens of crashes blamed for the deaths of 78 people in the past 10 years alone. And despite evidence they knew all along, the manufacturer Robinson and the Civil Aviation Safety Authority did nothing. Worse still, they're now facing the same deadly problem with the smaller R22.

2The Baby Lab It's a question people have asked for as long as there have been people: are human beings inherently good? Are we born with a sense of morality or do we arrive blank slates, waiting for the world to teach us right from wrong? Or could it be worse: do we start out nasty, selfish devils, who need our parents, teachers, and religions to whip us into shape? The only way to know for sure, of course, is to ask a baby. But until recently, it's been hard to persuade them to open up and share their secrets.
