It took more than a few nuts and bolts, but the world's largest jet engine, the GE9X, has finally been attached to the wings of the world's largest twin-engine jet, the Boeing 777X

The plane maker recently released pictures of the long-awaited marriage of engine and plane, slated to take their maiden voyage together in 2019. How large is the world's largest engine? At 11 feet in diameter, the GE9X is as wide as the body of an entire Boeing 737

And it boasts a slew of cutting-edge GE technologies, including 3D-printed parts, fan blades made from fourth generation advanced carbon-fiber composites, and components made from a material that can withstand temperatures up to 2,400 degrees Fahrenheit.
