The gap between America's super-wealthy and the rest of us has grown so vast it's hard to even comprehend the sums they spend on their luxuries. But if you measure, say, a $200 million luxury yacht in terms of the average U.S. family's household income, the picture comes back into focus.

Australian investigators suspect a manufacturing defect in a Rolls-Royce engine may have caused the A380 Airbus fire on a Qantas flight earlier this month. The airline says it has filed a statement of claim that could enable it to take further legal action against Rolls-Royce.

The Qantas Airbus A380 engine explosion earlier this month caused at least $70 million worth of damage to the plane, according to a new report from insurance-consulting company Aon. And the bill from the incident, which caused no injuries, could fly much higher.

Half of the Rolls-Royce engines that power the A380 Airbus superjumbo jets may need to be replaced, according to the Qantas CEO. One of the engines caught fire and caused the emergency landing of a Qantas flight earlier this month.
