NEW YORK — Even before two battery failures led to the grounding of all Boeing 787 jets this month, the lithium-ion batteries used on the aircraft had experienced multiple problems that raised questions about their reliability.
Officials at All Nippon Airways, the jets’ biggest operator, said in an interview Tuesday that it had replaced 10 of the batteries in the months before fire and smoke in two cases caused regulators around the world to ground the jets.

Fascinating -- and the fascinating thing is NOT that this is a case of an unknown and little understood problem with technology, but that it's a case of a so far unknown management issue. It seems like the mortgage meltdown where many informed observers knew that things would end and end badly but the politics meant that nothing would be able to be done to prevent it.
