In 1901 it was used by him to win the Deutsch de la Meurthe prize for a flight from Parc Saint Cloud to the Eiffel Tower and back within thirty minutes.

[2] The winner of the prize needed to maintain an average ground speed of at least 22 km/h (14 mph) to cover the round trip distance of 11 km (6.8 mi) in the allotted time.

Similar to the No.5 but slightly larger, it had an envelope of varnished silk from which an elongated uncovered gondola was suspended by steel wires.

The 12 hp (9 kW) engine was mounted in the centre of the gondola and drove a two-bladed pusher propeller at the rear via a long driveshaft.

After an hour and a half of trials at the Longchamps racecourse he flew the craft to meet friends at a nearby restaurant, but on attempting to return to his base at Chalais-Meudon a series of mishaps ended with the gondola being damaged.

[5] However it was soon repaired and a first attempt at the Deutsch de la Meurth prize was made on September 19, ending when the airship was blown against some trees during preliminary trials, resulting in the envelope being punctured.

However, there was a short delay before his mooring line was secured, and at first the adjudicating committee refused him the prize, despite de la Meurthe, who was present, declaring himself satisfied.

[8] The airship was salvaged and returned to Paris where it was repaired, and on Easter Monday (i.e., on March 30, 1902) it was placed on exhibition in the Concert Room in the Crystal Palace Park in south London, where it attracted 10,000 visitors on the first day it was shown.
