Maybe this blog post should disappear into oblivion along with Rosetta.
Aerostatic experiment carried out at Versailles on 19 September 1783 in the presence of Their Majesties and of the Royal Family by Monsieur de Montgolfier with a balloon of a height of 52 feet and a diameter of 41 feet. This superb device, bearing the King's signature on a blue background, weighed 900 pounds. The balloon's ascent was accompanied by applause from all the spectators. Then it came back down at the Marechal Carrefour in the Vaucresson woods.
