(WASHINGTON) -- The FAA has given the thumbs-up to a plan by Boeing to get the ultra-high tech Boeing 787 Dreamliner flying again.
 
Two months after all Boeing 787 Dreamliners were grounded worldwide for fear of on-board fires, the FAA is giving Boeing the go-ahead to begin testing two Dreamliners with redesigned batteries onboard.  The test planes won't carry any passengers.  

The old Dreamliner batteries were short-circuiting, causing potentially dangerous smoke and fire.

Boeing hopes the fix will soon allow Dreamliners around the world to fly again.

"Our top priority is the integrity of our products and the safety of the passengers and crews who fly on them," said Boeing Chairman, President and CEO Jim McNerney, in a company release Tuesday.

"Our team has been working around the clock to understand the issues and develop a solution based on extensive analysis and testing following the events that occurred in January. Today's approval from the FAA is a critical and welcome milestone toward getting the fleet flying again and continuing to deliver on the promise of the 787," he said.
