Alright kiddo! I'll explain United Aircraft Corporation to you in a way you'll understand.
Imagine you want to make a toy airplane from scratch. You need a lot of different parts like wings, engines, and a cockpit. But it would take you so long to make all those parts on your own! That's why you might go to a toy store and buy all the different parts you need right there.
Well, airplanes are kind of like big versions of your toy airplane. So instead of going to a toy store, airplane companies like United Airlines go to a big company called United Aircraft Corporation for all the different parts they need to make airplanes.
United Aircraft Corporation is a company that makes lots of different parts for airplanes, like engines, landing gear, and even computer systems that help the pilot fly the plane safely. They also make whole airplanes, but they mostly make parts that other companies use to build their own airplanes.
So when United Airlines wants to make a new airplane, they can order all the parts they need from United Aircraft Corporation. This saves them time and lets them focus on putting all the parts together to make a new airplane, just like you can focus on putting together your toy airplane when you have all the parts you need!
