Robert Siegel speaks with Wall Street Journal reporter Andy Pasztor about the Australian Transport Safety Bureau's report on the Qantas Airbus that had to make an emergency landing last month after an engine exploded. The report details how in addition to the engine blowout, two other engines were failing, there were multiple electrical failures on board and problems with a leaking fuel system. The Australians found that a problem with a misaligned oil pipe was the culprit that caused the engine to explode.
