Credits to Jelybaca as I built this off their 747 and copied a few things from the description Ex. fetures and controls.

Many people consider the iconic, four-engine Boeing 747 to be the ‘Queen of the skies.’ However, there was once a time when the American manufacturer was also working on a shortened variant with three engines.

Nowadays, it is hard to imagine the Boeing 747 as anything other than a four-engine icon. However, in the 1960s and 1970s, Boeing was considering constructing a three-engine variant of the type. This tri-jet aircraft would have had one engine on either wing, with an additional engine mounted in the tail. This design would have been similar to the narrowbody Boeing 727, although obviously much larger.
