____ prepared if there was an emergency on your plane? Think about the last time you flew. Did you pay attention to the safety demonstration? If you ____ to sleep, you would have heard the flight attendant explain the location of the emergency exists. This information is vital. If there had been a fire, you ____ only about 90 seconds to get off the plane. It's unlikely that there will be an emergency on your flight, but if there is, the most important thing is to be ready.
