A Cathay Pacific flight from Boston has been forced to make an emergency landing after smoke in the cabin was reported minutes after take off.
Flight CX811, an A350-1000 bound for Hong Kong, stopped climbing at around 5,000ft, according to aviation news site Air Live.
The crew declared an emergency around 30 minutes after it departed from Boston Logan International Airport at 02.04 EST.
The flight then held over Massachusetts Bay to dump fuel before returning to BOS Airport, according to reports.
Flight trackers show it looping around multiple times off the east coast before making its way back.
Air traffic controllers cleared it for landing at the airport a little more than an hour after it took off, and it was met by emergency vehicles after landing.
Cathay Pacific has been contacted for comment.
Several flights have been cancelled from Boston this morning, with the airport warning customers to expect delays due to bad weather.
