So weird,Double-deck Douglas D-956-13 from 1965. First use of the name "DC-10."
The initial DC-10 configuration included a high wing, much better suited for a military airlifter. Douglas moved the wing down, creating a design that closely resembles the new Airbus A380. This design is similar to the later proposed MD-12. (Source: Unknown)
