A selection of the experimental flying oddities dreamed up by aeronautical engineers since the 1950s, many of which were built without the help of the advanced computing technology and sophisticated wind tunnel modelling used today.
While craft like the saucer-shaped Avrocar and the Vertijet, an aeroplane with the ability to take-off vertically, were cancelled and others failed to make it past the prototype stage, they nevertheless helped push forward the possibilities of the technology.
