Flight AA263 from Dallas to Beijing was rerouted to Alberta due to a medical emergency and mechanical issue.
The Boeing 787-8 Dreamliner was diverted to Edmonton and was then redirected to Calgary so it could land on the airports long parallel runway.
"I was a little nervous, because they kept talking about, oh, were having some issue and I was like what issue keeps you from landing a plane and then they starting letting out jet fuel and that was impressive, there was this giant billowy cloud by the engines, said passenger Josh Parish.
"You look on the monitor seeing the plane going round and round and round in circles and it was like whats going on with this, said passenger Robert Bales.
There was a medical situation that arose, passenger Timothy Zhang told CTV Calgary after clearing customs at the Calgary International Airport. The captain asked if there were any medical personnel on board to assist and volunteer. There were a couple of doctors and nurses who went and talked with this elderly lady. She was experiencing chest pain and had difficulty breathing. They got her on some oxygen and got her legs elevated and, based on their recommendation, the captain decided to divert the plane.
Another plane was sent from Dallas to continue the flight and a crew was also dispatched to fix the Dreamliner.
The passengers departed Calgary at about 7:00 a.m. and are expected to arrive in Beijing on Saturday morning.
Passengers who spent the night in Calgary after their flight was diverted because of a medical emergency and mechanical issue were back in the air on Friday morning.
Investigators have released images of two vehicles that may have been involved in an early morning hit and run that left a Calgary police officer seriously injured earlier this year.
An American Airlines passenger jet was en route from Texas to Beijing on Thursday when a pair of issues forced to make an early landing.
The Boeing 787-8 Dreamliner left Dallas-Fort Worth late Thursday morning, but experienced both a medical emergency and a mechanical problem in the first few hours of the flight.
It was flying north over Manitoba when it veered southwest through Saskatchewan and entered Alberta just east of Fort McMurray.
The plane continued on to Edmonton and circled the city before turning south to Calgary to utilize a longer runway.
It also had been fuelled for a lengthy non-stop flight, so the large plane did loops around Drumheller to burn fuel and reduce its landing weight before its final approach to Calgary.
American Airlines hasn’t released any details surround the medical emergency and mechanical issue, although one passenger said the plane had problems with its flaps.
The plane landed shortly before 5 p.m. local time and the 209 passenger and 13 crew members were put up in hotels overnight.
Another plane, with a maintenance team on board, will be sent from Dallas today and the passengers will continue their trip to Beijing.
