In an airplane cabin, a flight attendant is demonstrating how to use the oxygen masks in the event of a loss of cabin pressure. She is wearing a yellow life vest over her white shirt and a black skirt. With her left hand, she holds the yellow oxygen mask to the ceiling. The mask is connected to a long, thin, clear tube. Her right arm is raised to assist. The cabin walls are light blue with a horizontal stripe of red, white, and blue. A row of oxygen masks is recessed above her. A passenger in the foreground is holding a remote in his hands and watching the demonstration. Another passenger is sitting in the row in front of him. A small sign labeled "X-LUG" is on the wall beside the flight attendant.
