HovercraftIn 1959, a hovercraft crossed the English Channel for the first time. Having been shipped to France by tender, the world's first all metal hovercraft, SR.N1, crossed the Channel between Calais and Dover in 2 hours 3 minutes on 25th July with Captain Peter Lamb piloting, Mr John Chaplin as navigator and the inventor, Mr. (later Sir) Christopher Cockerell in his own words as 'moveable ballast' on board. It was 50 years to the day that Louis Blériot made the first crossing of the Dover Strait by aeroplane. |
