Shoreham airport, founded in 1910, is the oldest airport in the UK and the oldest purpose-built commercial airport in the world. Yet aviation began in Sussex far earlier, with balloonists making landfall at Kingsfold near Horsham in 1785. These early activities attracted much attention, with some 30,000 people gathering at Black Rock in Brighton, as well as on the surrounding hills, to watch the first balloon ascent from the town in July 1821 - using coal gas from the recently opened gas works. That particular balloonist, Charles Green, later became immortalised by Charles Dickens in his Sketches By Boz. The military were quick to appreciate the potential benefits of aerial observation and in 1880 balloons were deployed for the first time at the annual Volunteer Review at Brighton. Often wind conditions were not favourable for balloons, which prompted the army to consider employing kites and in June 1903 an international competition was held on the South Downs near Findon to see if kites could lift a man into the air. While this was found to be possible, it proved a terrifying experience for the unfortunate pilots. Before powered flight became a reality, it was gliders which were the first heavier than air machines to take to the skies. In 1902 Mr Jose Weiss began launching unmanned gliders off a ramp at Houghton Hill near Amberley, which flew up to two miles. But soon the internal combustion engine made powered, controlled flight a reality and on 7 November 1908, Alec Ogilvie flew a Wright Brothers biplane along the coast at Camber. By the time war broke out in 1914, the people of Sussex had seen the Brooklands to Brighton air race and the establishment of flying schools at Shoreham and Eastbourne. After the Armistice, aviation started becoming increasingly expensive and increasingly regulated. The halcyon days of swashbuckling amateurs taking to the skies in untested contraptions was drawing to a close. AUTHOR: Having lived in Sussex for many years, the late Roy Brooks developed a deep interest in the county's aviation heritage. Over many years he delved deep into various archives and libraries to build up this remarkable insight into the early history of flight. 100 b/w illustrations
