The wide body L-1011 was Lockheed's first entry into the jet passenger aircraft market. The L-1011 was an advanced design, quiet, efficient and touted as the safest aircraft in the air. It sported a highly advanced auto pilot, and was the first aircraft to be certified by the FAA for CatIIIc auto landing. In spite of this, sales were disappointing in the face of competition from the Boeing 747, and the Douglas DC-10, which it resembled. Only 250 were built, after which Lockheed abandoned the commercial aircraft market entirely.
