The Boeing Company (NYSE: BA ) 787 Dreamliner is the world's most technologically advanced commercial jet, but it doesn't fly. Regulators worldwide have kept the global 787 fleet grounded since mid-January, after a series of malfunctions and safety concerns — which Boeing CEO Jim McNerney initially referred to as normal "squawks" — spectacularly culminated in battery fires on two separate aircraft. On Friday, Boeing came out with an ambitious plan to right that wrong.
