Balloonistics

The  first gas balloon  made its flight in August 1783. Designed by professor  Jacques Charles  and  Les Frères Robert , it carried no passengers or cargo. On 1 December 1783 their second hydrogen-filled balloon made a manned flight piloted by Jacques Charles and  Nicolas-Louis Robert , 10 days after the first manned flight in a  Montgolfier   hot air balloon .
