"Aviation in Britain Before the First World War" Nulli Secundus II leaving the ground at the start of its maiden voyage, a large crowd is looking on and part of one of the airship sheds is visible in the background. The two poles to the left of the airship were used by Cody to fly his tethered powered kite. This was an enlarged version of the original Nulli Secundus and used the same Antoinette Engine. The airship was only operated for around two months before being scrapped.
