Here is a concise description of the video: The video takes place inside of a passenger airplane. A flight attendant is demonstrating how to put on an oxygen mask for the passengers. She is standing in the aisle between the rows of seats and is wearing a black uniform and red scarf. She is holding an oxygen mask in her hands and placing it over her mouth and nose. Several passengers are seated in the rows of seats. A red curtain hangs next to the aisle on one side.
