Holy shit. What a champ. No training and freaking aced it.
Bobik and ZIB
Bobik (Бобик, common Russian name for small dog) ran away just days before his flight was scheduled to take place on 15 September 1951. A replacement named ZIB (ЗИБ, a Russian acronym for "Substitute for Missing Bobik", "Замена Исчезнувшему Бобику" Zamena Ischeznuvshemu Bobiku), who was an untrained street dog found running around the barracks, was quickly located and made a successful flight to 100km and back.
