In 1908 the French industrialist Adolphe Clément-Bayard diversified into the aviation industry. His first project was a lens-shaped airship designed by Louis Capazza, which was never built. He then collaborated with the Société Astra (Société Astra des Constructions Aéronautiques) on the manufacture of a more conventional craft. Astra were responsible for the manufacture of the envelope, and Clement-Bayard took responsibility for the nacelle and engine. After this collaborative effort the company started manufacturing the envelopes as well, at a new factory in La Motte-Breuil built in anticipation of orders from the French Army, who had decided to commence airship operations. The Clément-Bayard No.1 airship was offered to the French government but was too expensive so it was bought by Tsar Nicholas II for the Russian army. In 1910 the ''Clément-Bayard No.2'', piloted by Maurice Clément-Bayard, was the first airship to cross the Channel, travelling over 380 km in 6 hours.〔(Nos belles anciennes – Clément-Bayard, Profile of Gustave Adolphe Clément )〕 The army ordered 3 copies. The airship hangar in La Motte-Breuil is still maintained by Clément-Talbot Ltd. == Clément-Bayard dirigibles == Seven Clément-Bayard airships were completed.〔(Hydro Retro, Clément-Bayard, pdf (French) Clément-Bayard, sans peur et sans reproche par Gérard Hartmann )〕〔 * N° 1 was long, wide, capacity, powered by 2 Clément-Bayard 115 hp engines.
