Cathay 747 loses panel, lands safely in Vancouver
 

VANCOUVER -- A Cathay Pacific plane that lost its air-conditioning panel mid-flight landed without incident at Vancouver International Airport early Tuesday morning.
The Boeing 747 aircraft originated at New York's JFK Airport and landed without incident at YVR at about 3 a.m.
"A panel that covers the air-conditioning unit in the belly of the aircraft became detached and is missing," said Bill Yearwood, regional manager of the Transportation Safety Board.
"The ground crew and flight crew, I gather, determined this after they landed here in Vancouver."
The missing piece didn't affect the pressurization in the plane's cabin and there were no apparent handling changes.
Reports say that passengers heard a loud sound during the flight, but the Transportation Safety Board could not confirm if the the sound was linked to the panel.
A replacement panel is being flown to Vancouver. After the airplane has been examined, it will be allowed back into service.
"From time to time, there are panels that are lost off aircrafts, but it's not frequent," Yearwood said.
"We don't hear of it very often."
