Why now? What's changed?

Through the testing of batteries and review of data, Boeing believes it now is to the point where further testing of Dreamliner batteries and components is needed while they are in flight. In other words, there are tests needed to either confirm or eliminate whether certain conditions (vibration, etc.) in flight did or did not contribute to the two Dreamliner battery fires.

There is no word on when the FAA will respond.

NOTE: This is only for Boeing 787's, not those delivered already to customers like United Airlines.
