||1783: The first experimental hydrogen-filled balloon left the Champs de Mars, Paris, unmanned, and reached 900-m altitude. Under the auspices of the French Academy of Sciences, Jacques A.C. Charles sent up a 13-ft (4-m) diameter hydrogen- filled balloon of rubber- coated silk. One of the spectators was the American ambassador to France, Benjamin Franklin. The gas had been manufactured, beginning on 23 Aug 1783, by pouring 225-kg of sulphuric acid over half a ton of scrap-iron. Able to lift about 9-kg, it traveled 24-km in about 45 minutes. The balloon descended close to the little village of Gonesse, where frightened local farmers attacked it with pick axes and spades, leaving only torn remains.

||1784: James Tytler made the first balloon ascent in Britain in a hot-air balloon at Ediburgh, Scotland. He exhibited his "Grand Edinburgh Fire Balloon" in the uncompleted dome of Robert Adam's Register House. It was barrel-shaped, 40-ft tall, 30-ft diameter, with hot air produced by a stove. He wore a cork jacket for protection, and sat a small wicker packing case below the balloon. Before a small number of onlookers, the balloon rose to 350 feet in the air, travelled half a mile, and landed in Restalrig village. Tytler reported that the flight was "most agreeable with no giddiness" and that he "amused himself by looking at the spectators below." Four days later, a large paying audience saw it, but that flight was much less successful.
