The following description is entirely fictional.
The MD-14 was a wide-body passenger aircraft development project conceived by McDonnell Douglas around 2000, following the MD-12 project. The project was based on the existing MD-11 and made significant improvements, the most notable feature of which was the change from the original three-engine layout to a twin-engine design that was more in line with the trend of the new generation.

The MD14's fuselage is constructed from a combination of aluminum alloy and carbon fiber composite materials.
The nose section is made of aluminum alloy, similar to the MD11, while the midsection of the fuselage uses carbon fiber composite materials. The tail section is made of aluminum alloy.

The engine used is the GE90-76B turbofan engine.

Plus, speaking of fictional airliners, I remember offering you a fictional triple decker called the Boeing New Giant Transporter last year, and I hope we still see that massive jet be brought to life one day however much longer that might take. =D
Oh nice, we have a fictional McDonnell Douglas airliner named the MD-14, based off the real-life MD-11 but as a twin-jet, and I must say that the MD-14 would have been an amazing plane for to see fly over me and my family if it were real. ;)
