JetZero, a company from California, will build a new plane factory in North Carolina. This will make many jobs, about 14,500, in ten years. The company will spend $4.7 billion to build the Z4 plane. This plane uses much less fuel than other planes. United Airlines and Alaska Airlines want to buy these planes. The factory will also have a place to study new plane parts. JetZero wants to start using these planes around 2030. They want to make 20 planes each month. The plane will have 250 seats and can fly very far.
