fatality per mile basis, air transport is the safest – six times safer than travelling by car and twice as safe as rail." When measured by fatalities per person An aviation accident is an event during aircraft operation that results in serious injury, death, or significant destruction. An aviation incident is any operating event that compromises safety but does not escalate into an aviation accident. Preventing both accidents and incidents is the primary goal of aviation safety. The most common causes of these accidents and incidents are technical or mec Evacuation slides, to aid rapid passenger exit from an aircraft in an emergency situation Advanced avionics, incorporating computerized auto-recovery and alert systems Turbine engines with improved durability and failure containment mechanisms Landing gear that can be lowered even after loss of power and hydraulics Measured on a passenger-distance calculation, air travel is the safest form of transportation available: Figures mentioned are the ones shared by the air industry when quoting air safety statistics. A typical statement, e.g., by the BBC: "UK airline operations are among the safest anywhere. When compared against all other modes of transport on a fatality per mile basis, air transport is the safest – six times safer than travelling by car and twice as safe as rail."
