Most people don't pay attention to flight attendants' instructions before their flights take off, but what they have to say is important.
But just in case you miss the directions about what to do in case of emergency, there's now an app for that.
The Human-Computer Interaction Laboratory at Italy's University of Udine has created a smartphone app called "Prepare for Impact" that simulates aircraft emergencies in first person.
Supporters of the app say a first-person simulation might be more helpful for emergency preparedness. The university's research suggests a simulation is far more effective than passive education, like the faded and wrinkled airplane safety cards placed in front of each seat.
"Prepare for Impact" simulates several different real-world scenarios, including a crash landing, a water landing and a ground collision. It also simulates complications that might arise in any of the scenarios, like fire, smoke or flooding.
The free app is available for both iOS and Android.
