787 flights to resume 'within weeks'

Boeing bosses said today commercial flights of its grounded 787 jets would resume “within weeks, not months”, with a third of safety tests already completed.

They said they had not pinpointed the causes of the two battery problems that resulted in the world grounding of the technologically-advanced Dreamliner planes.

But Boeing chief project engineer Michael Sinnett said a new design had many layers of safeguards to prevent battery fires and overheating.

It has measures to contain the problem from spreading and to keep the aircraft safe, even if batteries malfunction again, he said.

The executives made the comments in Japan, where All Nippon Airways was the launch customer for the 787.
