Permission to resume Boeing's 787 may come as early as Thursday: Japan govt

TOKYO (REUTERS) - Japan's Civil Aviation Authority said final permission to resume Boeing Co's grounded Dreamliner flights may come as early as Thursday.

Boeing engineers on Monday began installing reinforced lithium-ion battery systems on the Boeing 787 jets in Japan, starting with launch customer All Nippon Airways.

That should make the first 787 ready to restart flights in about a week.
