Is the 787 a failure ?

"Regulators on Friday approved a revamped battery system for Boeing Co's
787 Dreamliner, a crucial step in returning the high-tech jet to service
after it was grounded in January because the plane's lithium-ion
batteries overheated.

The Federal Aviation Administration said it had approved a package of
detailed design changes, a move that allows Boeing to issue a service
bulletin and make repairs to the fleet of 50 planes owned by eight
airlines around the world. Other global regulators also must approve
Boeing's new design but were expected to act quickly once the FAA gave
its blessing.

The FAA action all but ends a grounding that has cost Boeing an
estimated $600 million, halted deliveries and forced some airlines to
lease alternative aircraft."
