Uncontained engine failures occur in about 1 in 300 of engine failures, and those odds are even better with newer, stronger engines. When an engine fails uncontained, it always will force the airplane to an abrupt stop or an unscheduled landing, and will almost always make news. Generally, the cowling will stay somewhat intact, with the fan blades fired out through slash-like holes. When these are thrown into the fuselage at such a high velocity, it will cause the cabin to rapidly decompress, and becomes a knife flying into the cabin, killing or severely injuring any passenger in its way. If it strikes a fuel line, it may cause a leak or complete fuel tank failure. In all cases, standard procedure is to shut down the engine ASAP, assess damage, shut down or reroute any systems affected by the damage, and divert to nearest suitable airport.
