History Blériot Aéronautique
Blériot XI Channel Crossing



The Daily Mail prize was first announced in October 1908, with a prize of £500 being offered for a flight made before the end of the year. When 1908 passed with no serious attempt being made, the offer was renewed for the year of 1909, with the prize money doubled to £1,000. Like some of the other prizes offered, it was widely seen as nothing more than a way to gain cheap publicity for the paper: the Paris newspaper Le Matin commenting that there was no chance of the prize being won. The English Channel had been crossed many times by balloon, beginning with Jean-Pierre Blanchard and John Jeffries's crossing in 1785

The Blériot Memorial, the outline of the aircraft laid out in granite setts in the turf (funded by oil manufacturer Alexander Duckham), marks his landing spot above the cliffs near Dover Castle. 51.1312°N 1.326°E. The aircraft which was used in the crossing is now preserved in the Musée des Arts et Métiers in Paris.

At 4:15 am, 25 July, watched by an excited crowd, Blériot made a short trial flight in his Type XI, and then, on a signal that the sun had risen (the competition rules required a flight between sunrise and sunset), he took off at 4:41 to attempt the crossing. Flying at approximately 45 mph (72 km/h) and an altitude of about 250 ft (76 m), he set off across the Channel. Not having a compass, Blériot took his course from the Escopette, which was heading for Dover, but he soon overtook the ship. The visibility deteriorated, and he later said, "for more than 10 minutes I was alone, isolated, lost in the midst of the immense sea, and I did not see anything on the horizon or a single ship". The grey line of the English coast, however, came into sight on his left; the wind had increased, and had blown him to the east of his intended course. Altering course, he followed the line of the coast about a mile offshore until he spotted Charles Fontaine, the correspondent from Le Matin waving a large Tricolour as a signal. Unlike Latham, Blériot had not visited Dover to find a suitable spot to land, and the choice had been made by Fontaine, who had selected a patch of gently sloping land called Northfall Meadow, close to Dover Castle, on top of the cliffs. Once over land, Blériot circled twice to lose height, and cut his engine at an altitude of about 20 m (66 ft), making a heavy "pancake" landing due to the gusty wind conditions; the undercarriage was damaged and one blade of the propeller was shattered, but Blériot was unhurt. The flight had taken 36 minutes and 30 seconds..

The Blériot Type XI was designed primarily by Raymond Saulnier, but it was a natural evolution from earlier Blériot aircraft, and one to which Louis Blériot himself made substantial contributions.
