Boeing's 787 Dreamliner back in the air in Japan

Boeing's 787 Dreamliner is back in the air after being grounded for three months over faulty batteries.

Japan's All Nippon Airways became the second carrier to test the 787 aircraft, after aviation regulators approved the resumption of flights.

Japanese airlines are the biggest owner-operators of Dreamliners, but commercial flights may not commence till June.

The BBC's Rupert Wingfield-Hayes reports from ANA's facility at Haneda airport.
