Along with Joseph Montgolfier, he was one of six passengers on a second flight on 19 January 1784, with a huge Montgolfier balloon Le Flesselles launched from Lyon. Four French nobles paid for the trip, including a prince. Several difficulties had to be overcome. The wallpaper used to cover the balloon's envelope became wet because of extreme weather conditions. The top of the balloon was made of sheep- or buckskin. The air was heated by wood in an iron stove: to start, the straw was set on fire with brandy. (In other tests charcoal or potatoes were used). The balloon had a volume of approximately 23,000 m³, over 10 times that of the first flight, but it only flew a short distance. The spectators kneeled down when the balloon came down too quickly. That evening the aeronauts were celebrated after listening to Gluck's opera, Iphigénie en Tauride.
