(Adds comment from airline, share price)
BOSTON, July 18 A Boeing Co 787
Dreamliner plane operated by Japan Airlines Co Ltd
returned to Boston's Logan International Airport on Thursday
after a mechanical indicator alert came on, driving Boeing
shares 1.7 percent lower.
"The pilot decided to turn back out of an abundance of
caution," airport spokesman Richard Walsh told Reuters.
Carol Anderson, a spokeswoman for Japan Airlines, confirmed
the move but offered no further details.
"As a standard precautionary measure due to a maintenance
message indicator, JL007 bound for Tokyo-Narita is returning to
Boston Logan for checks," she said.
The after-hours share fall reflected lingering concerns
about Boeing's newest plane, which remains under investigation
after a fire on board a parked 787 at Heathrow Airport in London
