In the case of large airliners, crashes typically end in death. The planes have an average cruising height of 30,000-40,000 feet above the ground and carry more than 50,000 gallons of fuel. There is little room for error. If the plane hits the ground, there are times that there are survivors, but the injuries are usually quite severe.
Some accidents are simply unavoidable. Bird strikes and severe weather can bring down an otherwise perfectly flown and well-maintained aircraft. Airliner crashes can also be caused by equipment malfunction, defective airplane parts, pilot error and improper runway maintenance. If it is found that the pilot was intoxicated or on some kind of improper medication while operating a plane, the pilot made an incorrect maneuver, or that the plane was allowed to fly without undergoing proper maintenance, responsible parties can be held accountable through a lawsuit.
