It was discussed previously in this forum that the MD
-11 and the DC-10 are very popular aircraft with cargo operators. I find that interesting, but there were some explanations given. First, these models seem to be fast, can hold sufficient cargo with standard containers, are reliable, and there is a market with plenty of second-hand aircraft of this type.
Now here comes my first question.
Is it coincidence that an aircraft with three
engines enjoys such popularity or is there a deeper reason behind it? Why not a twin engine aircraft? The Airbus A300B4 is also popular with freighter airlines, but not as popular as DC-10s and MD
-11s, isnt it? I am sure there are plenty of old twin engine airplanes available.
Why is the Lockheed Tristar not as popular with freighters than DC-10 or MD
-11? It also has three engines, thus the name.
It wasn't as widely used as the DC-10, but is has a good reputation and was very advanced.
