The first use of an air-dropped bomb (actually four hand grenades specially manufactured by the Italian naval arsenal) was carried out by Italian Second Lieutenant Giulio Gavotti on 1 November 1911 during the Italo-Turkish war in Libya – although his plane was not designed for the task of bombing, and his improvised attacks on Ottoman positions had little impact. These picric acid-filled steel spheres were nicknamed "ballerinas" from the fluttering fabric ribbons attached.
