 Japan's largest airline, ANA, and its competitor JAL have each grounded their entire fleet of Boeing 787 Dreamliners after an emergency landing due to a smoke alarm in the cockpit – the most dramatic of a spate of incidents involving the troubled aircraft over the past week and since its inception. The aircraft has been hit by half a dozen incidents in the past week, including two fuel leaks, a battery fire, a wiring problem, a brake computer fault and a cracked cockpit window.

 On Wednesday, ANA's flight NH 692 left Yamaguchi Ube in western Japan at 08:10 local time (23:10 GMT) and headed for Tokyo's Haneda airport. "There was a battery alert in the cockpit and there was an odd smell detected in the cockpit and cabin, and [the pilot] decided to make an emergency landing," said Osamu Shinobe, an ANA vice president, at a news conference. All Nippon Airways said the plane had been evacuated, with its eight crew and all 129 passengers exiting safely on inflatable slides. Paul Lewis, a spokesman for Boeing, told the BBC that the planemaker was "aware of the diversion of a 787 operated by ANA to Takamatsu in western Japan". Boeing spokesman Marc Birtel told Reuters: "We've seen the reports, we're aware of the events and are working with our customer."

 The concerns have spread beyond Japan, however, not least because the Dreamliner was seen as Boeing's flagship new aeroplane and had attracted orders from many of the world's biggest and best-known airlines. Last week, the US Federal Aviation Administration started a joint review with Boeing of the design, manufacturing and assembly of the Dreamliner. On Tuesday, Japanese authorities said they would conduct an inquiry after two successive fuel leaks on a different 787 operated by Japan Airlines.
– Almost half the world's fleet of Dreamliners has been grounded after yet another incident, this time involving an emergency landing. All Nippon Airways and Japan Airlines announced they were taking the new Boeing aircraft out of service after an ANA flight was forced to land after a smoke alarm went off in the cockpit, the Guardian reports. Cockpit instruments said there had been a battery malfunction. There were several minor injuries as the 129 passengers and eight crew were evacuated from the aircraft. The ANA incident follows a host of other Dreamliner incidents in recent weeks, including a fire and two fuel leaks. The two Japanese airlines have 24 out of the 50 Dreamliners currently in service. More than 800 others have been ordered by airlines around the world, but Boeing is now facing a major image problem. "You're nearing the tipping point where they need to regard this as a serious crisis," an aviation analyst tells the BBC. "This is going to change people's perception of the aircraft if they don't act quickly."
