Just imagine what you would think of this lady passenger if her failure to pay attention to the safety briefing had been overlooked and she was not able to open the emergency exit leading to the unnecessary death of a close relative of yours such as your Wife, Son, Daughter, Sister, Husband, Mother, Father etc
It is less than a week since those people in Moscow burned to death, think how terrible it must be to be stuck in an aircraft that is on fire and not be able to get off, how tragic would it be if you were stuck because some one would not spare a couple of minutes of their time to pay attention to a safety briefing?
