US aviation bosses expected to announce Dreamliner review
There are reports that US aviation authorities will announce a review into Boeing's 787 Dreamliner later after two more incidents involving the aircraft.
An All Nippon Airways (ANA) plane landed in Japan earlier, after a crack appeared in a cockpit window.
Meanwhile oil was found leaking from an engine of one of the airline's other 787s.
The latest incidents bring the total to five in as many days.
A press conference is expected at 2.30pm.
