• The UK’s first aircraft manufacturers – Horace, Eustace and Oswald Short – have been commemorated with an English Heritage blue plaque placed on their former workshop in Battersea. Unveiled this week by Jenny Body – the first female president of the Royal Aeronautical Society, the plaque can be found at the railway arches near Queen’s Circus where the brothers, who lived nearby in the Prince of Wales Mansions, worked on ballooning and first made the transition to aircraft construction. Among their firsts was the construction of the first British powered aircraft to complete a circular mile of flight and the creation of Britain’s first ever purpose-built aircraft factory (it was located on the Isle of Sheppey in Kent).
