Sometimes bigger is definitely not better. All Nippon Airways realized that on Tuesday, when decided to ground all Boeing 787 Dreamliner jets immediately after experiencing multiple problems. On Wednesday in Japan, one of the airline’s flights made an emergency landing after a battery alarm alert. ANA had several other problems with the Dreamliners but would not detail them. Last week, the FAA announced it would investigate the 787s after a fire aboard a Japan Airlines flight in Boston and a leak on a Dreamliner the next day.
