SAN FRANCISCO — Two mishaps Friday with Boeing 787 Dreamliners sent the aerospace company's shares sharply lower on concerns the troubled aircraft might again be grounded.
Fire broke out Friday on an Ethiopian Airlines Boeing 787 at London's Heathrow Airport, prompting a temporary shutdown of the airport's runways as firefighters rushed to the stricken aircraft.
Boeing said it is aware of the fire at Heathrow and tweeted: "We're working to fully understand and address this."
Soon after, charter carrier Thomson Airways reported an unspecified technical problem on one of its 787s forced the plane to abandon its flight to Florida from England.
The good news? Initial reports indicate the Ethiopian Airlines aircraft was empty and parked at a remote corner of Heathrow at the time the fire broke out.
Meanwhile, the diverted Thomson flight made it safely back to Manchester.
But none of this was good news for Boeing's share price, which tumbled as much as 6 percent, a move that weighed on an already weakened Dow Jones Industrial Average, which includes Boeing among its 30 listed companies.
Boeing shares were last trading 4.5 percent lower at $102.30. The move knocked about $3.8 billion out of Boeing's market capitalization.
