The inside of the 787 is the most noticeable feature. The windows are much bigger on the 787 than on other planes because the plane is made mostly of composite, which is stronger than the aluminum which is used on most other planes. Also, the windows of the plane don't use slide-down shades like most planes. Instead they have buttons which can make the window darker or lighter. The inside of the plane also uses LED lighting. This lets the plane change the colors of the lights inside.
