Question: what is the difference between a dc 10 and an md 11?
Answer: The MD-11 has winglets (the 'tipped up' parts at the ends of the wings). The DC-10 does not. The DC-10's horizontal stabilizer (tail) is larger than the MD-11's. The DC-10's tailcone is rounded, the MD-11's is squared off (like a flathead screwdriver).
