7 January 1785: On a clear, calm day, Jean-Pierre François Blanchard and Doctor John Jeffries flew across the English Channel in a hydrogen-filled balloon. They lifted off from Dover Castle, Kent, England at about 1:00 p.m. The journey to Guînes, Pas-de-Calais, France, took about two and a half hours.
The balloon was approximately 8.2 meters (27 feet) in diameter. A gondola was suspended beneath the gas envelope, equipped with oar-like devices that were intended to steer and propel the light-than-air craft.
With sufficient buoyancy to just lift the two aeronauts and their equipment, the Channel crossing was made at a very low altitude. During the flight, all ballast, their equipment and most of their clothing were jettisoned. They crossed the French coast at about 3:00 p.m. and at 3:30, came to rest in a clearing in the Felmores Forest, near Guînes.

Another nice blogpost. Plus i learned two new things:
1.) About the flight itself.
2.) The flag shown in the 2nd picture is not a mistake – it is probably a pun by the painter. This flag indeed existed in France – but only for 9 days before it was revoked. It is the flag of the so-called 2nd Republic, and was official for 9 days in early spring 1848.
And to add insult to injury, the painter depicted it wrong – 90° to the side, and in the wrong order of colours (red should be in the middle). 😉
