The first Vickers Vulcan was delivered on 30 May 1922, and entered service on Instone Air Line's London to Paris route two days later. Instone had some modern ideas, including uniformed staff and 'City of' aircraft names. Photo from: Bibliothèque nationale de France - Gallica

Qantas was coerced into buying two 8-passenger Vickers Vulcans. Nicknamed the Flying Pig, it turned out it flew like one. G-EBET was assembled at Point Cook, Victoria, and flown to Longreach, Queensland, for Qantas to test. It failed dismally, unable to reach the promised altitude even when the payload was halved. Qantas cancelled its order. What happened to -EBET is not recorded. Photo from: National Library of Australia
