Video footage recorded by a passenger waiting in the airplane terminal shows crew members dancing and posing.

Swiss International Air Lines employees are facing an investigation by angry bosses after they were caught dancing and taking pictures on the wing of a Boeing 777. The video that has gone viral was captured by a traveler waiting in the airport terminal.

In the clip, a female flight attendant dances on the plane’s wing, and a man joins her. A second man, presumably a senior flight attendant, appears and assumes a bodybuilder pose.

The clip also shows two ground crew members on the tarmac posing for a photo in front of the plane’s engine.

The footage was recorded earlier this month and drew the ire of Swiss International Air Lines management.

The airline responded to the viral video by saying, “This kind of behavior will not be tolerated.

” The fun-looking behavior in the video is life-threatening,” Swiss spokesman Michael Pelzer said.

” The wings of the Boeing 777 are about five meters [16.4 feet] high. The fall could be devastating when falling from that height onto a hard surface.”

According to The New York Post, Mr. Pelzer doubled down, saying that the crew should only climb onto the plane’s wings in case of an emergency, such as an evacuation, and debunk the employees’ “unprecedented” behavior.

Airline executives, including Vice President Martin Knuchel, called for an end to such antics, saying he was “angry and frustrated.”
