To learn what your chances are, plug in the airport you're flying out of and into, the airline you're on, and the aircraft model. It'll take historical crash data and calculate your chances of doom into a hard number (i.e., 1 in 2,783,874), then the app translates that into even simpler terms, i.e., "you'd expect to go down if you took this flight very day for 7,627 years." Aviophobiacs rejoice!
