GREENE: Engineers are starting to repair some of Boeing's 787 Dreamliner planes today. They are installing new batteries - ones that hopefully don't overheat.
STEVE INSKEEP, HOST:
All 787 Dreamliners were grounded in January - you may recall - after a lithium ion battery caught fire and another was found smoking. The engineers were installing reinforced batteries on a 17-plane fleet of Japan's All Nippon Airways. Now before the planes can carry customers again, ANA plans hundreds of test flights.
Boeing estimates it has lost $600 million because of the battery failures. Transcript provided by NPR, Copyright NPR.
