Why Boeing 747s have a giant hump in the front..?

Boeing 747

Do you know why? Turns out, that hump has been around since the ’60s. Back then, everyone was excited for supersonic commercial flight. Which could have taken you from New York to Paris in a few hours. A Boeing 747 that took 9 hours for the same trip would soon become obsolete. So the Boeing company planned ahead with its 747 model. The plane was designed for both passengers and cargo. So, if passengers stopped flying it, the 747 was still useful. That’s where the iconic hump comes in.

Engineers decided to turn the front of the plane into a giant door. The nose would open up, making it easy to load tall cargo. But there was just one problem: The cockpit was located over the nose. So, it was moved to a second deck. The extra space, behind the cockpit, was initially reserved for first-class passengers. And had a full bar and lounge until the 1973 fuel crisis. Over the years, the deck has grown in size.. Today, the upper deck on a Boeing 747-8 is the same length as a Boeing 737. The Boeing 747-8 is the longest airliner in the world. As well as on of the most recognizable aircraft – because of that iconic hump.


The Boeing 747 is one of the most recognizable aircraft in the world. One of the reasons for that, besides its popularity, is because of its distinctive hump on the roof. The hump was an innovative solution to a design issue.
