The fuselage is the main section of the airplane. It houses the cabin, where the passengers sit during flight, the cockpit, where the pilots sit during flight, as well as the baggage compartment. The wings, engine, and tail section—or empennage—attach to the fuselage. In most single-engine airplanes, a firewall separates the engine from the fuselage to protect the occupants in the rare event of an engine fire.
