Extract
In the fourteenth Henson and Stringfellow lecture delivered to the Society earlier this year, Speechley compared the development of the helicopter with that of conventional fixed-wing aircraft. He pointed out that some ten years elapsed between Kittyhawk and the mass production of military aircraft which occurred during the First World War, and that there were a further two decades before the commercial breakthrough of the DC2/3 aircraft. Initial helicopter progress followed a similar pattern but the commercial breakthrough is still awaited more than twenty years after the beginning of large-scale military procurement.
