The beleagured Boeing 787 Dreamliner is finally on its way to being fixed - the US airline regulator has approved a series alterations to the battery - which had raised concerns after emitting smoke.

Here's the BBC report:

"This comprehensive series of tests will show us whether the proposed battery improvements will work as designed," said US Transportation Secretary Ray LaHood. "We won't allow the plane to return to service unless we're satisfied that the new design ensures the safety of the aircraft and its passengers."

50 787 planes are currently grounded, after a fire started in a pack of batteries of one of the 787s from Japan Airlines.
