The same sort of credit belongs to the conduct of the balloon factory under Mr. Mervyn O'Gorman, who had charge of it during that very crucial period from the autumn of 1909 to the summer of 1916. When he took over the factory he found at Farnborough one small machine shop, one shed for making balloons, and one airship shed. The workers were about a hundred in number, fifty men and fifty women. Seven years later, when Lieutenant-Colonel O'Gorman was appointed to the Air Board as consulting engineer to the Director-General of Military Aeronautics, the hundred had swollen to four thousand six hundred, and the buildings situated on the forest land of Farnborough had increased and multiplied out of all recognition. This development was made necessary by the war, but it would have been impossible but for the foresight which directed the operations of the period before the war. The factory, working in close co-operation with the Advisory Committee and the National Physical Laboratory, very early became the chief centre for experimental aviation with full-sized machines. Systematic and rapid advance was hardly to be hoped for from unaided private initiative. Many private makers of machines were zealous and public-spirited, but there was no considerable private demand for aeroplanes, and a firm of manufacturers cannot carry on at a loss. Poor though it was in resources, and very meagrely supported by Government grants, the factory was what the country had to depend on; and it rose to its opportunities.
