Federal investigators are trying to determine why debris fell from the engine of a new Boeing 787 Dreamliner at a South Carolina airport yesterday.

The debris fell onto a runway at Charleston International Airport and into the grass.

That sparked a fire that closed the airport for more than an hour.

The plane was undergoing preflight testing at the time.
