Plural of fuselage; the main body structures of aircraft that hold passengers, cargo, and crew.
From French fuselage meaning 'streamlined shape,' derived from fusele (spindle-shaped). The term applies because aircraft bodies were designed to be long and tapered like spindles.
The fuselage is why aluminum became essential to aviation—its lightweight strength allows planes to be both sturdy and fast, fundamentally enabling the entire age of air travel.
