The first flight over Penzance was a short affair lasting just 3 minutes at a height of 200 feet. This was achieved in a rather fragile biplane called a Farman with a propeller in the rear. This was around 6.00 p.m. on Saturday July 23rd, 1910. The pilot was the renowned Claude Grahame-White whose purpose was to fly over the three fleets assembled in the bay where they were expected to be informally reviewed by the recently crowned King George V. Poor weather had delayed the flight and high winds curtailed this first effort.
Grahame-White’s second flight from Marazion at 9.00p.m. that same evening was more impressive. It lasted some 15 minutes over the now illuminated fleet. Among the 200 ships present he was able to identify the flagship of the Home fleet, The Dreadnought, and the Admiralty yacht, The Enchantress. It had been his intention to show the vulnerability of the Navy to aerial attack. He had been supported in this endeavour by the photographer of The Daily Mirror, Vaughan T Paul. Grahame-White had learnt to fly at Reims under Bleriot who was the first to cross the Channel, the previous year in 1909. The next month Grahame-White flew his Farnham biplane over Washington landing close to the White House.
Despite the attention which it attracted this was not the first heavier than air flight to take place in the Duchy. Jack Humphries, a Dental Surgeon from Fowey had observed bird flight and made at least two flights with gliders from nearby cliffs. In 1912, the French aviator Henri Salmet, with the financial support of Lord Northcliffe arrived with his Bleriot machine on the 14th of June in Falmouth. He had intended to fly over Lands End, however the headwinds proved too strong for the monoplane.
On 24th September 1913, the Hamburg born Gustav Hamel, just 24 years old, arrived at Trengwainton from whence he flew his Bleriot monoplane over Penzance where he could be seen clearly from the Market Place, Market Jew Street and then to Newlyn Coombe and on to St Ives and was greeted by a large crowd upon his return. After meeting Lord and Lady St Leven and the local M.P., Mr T. Bedford Bolitho who examined his aircraft. The energetic Hamel flew off once more at 5.30 and returned having fulfilled his ambition of being the first aviator to have flown over Lands End.
Hamel and Grahame-White collaborated in the development of Hendon airfield which became a flying school, a site for aircraft manufacture and later taken over by the R.A.F. and is now its museum. Ballooning at Hendon had taken place as early as 1862. Airship bases were built in Cornwall during 1915 and 1916. For example, the Royal Naval Air Station Mullion was developed on a 320-acre site near the village of Cury and the first airship transported here by train. This Lizard Airship Station was later to contain a hydrogen producing plant and a small Marconi transmitter. Its situation was ideal for attacking U-boats in accordance with the intentions of the First Sea Lord, Lord Fisher.
