Eurowings flight turns back due to mysterious odor in cabin

A Eurowings plane flying from Berlin to Manchester had to turn back around Monday after an "undefined odor in the cabin" was reported, according to the airline. 

"The aircraft was subsequently inspected without any findings," the airline said. "As a result, the flight will be delayed, and all passengers have already been informed by SMS."

No word on the source of the odor. 

One airport passenger posted on social media a video showing the plane on the tarmac surrounded by a number of fire trucks, surrounded by firefighters.
