On 7 January 1785 Jean-Pierre Francois Blanchard and John Jeffries, an American doctor, made the first trip across the English Channel in a hydrogen balloon in a trip that took 2-1/2 hours. They landed in a forest after being forced to throw overboard all ballast, equipment and even most of their clothing to avoid a forced landing in the icy waters of the English Channel.
The first air-mail letter was carried by balloon from England to France in 1785.
