Click start and join us on a relaxing hot air balloon ride over a calm lake. If you didn't know the hot air balloon is the first successful human-carrying flight technology. The French brothers Joseph-Michel and Jacques-Étienne Montgolfier developed a hot air balloon in Annonay, Ardeche, France and demonstrated it publicly on September 19, 1783, making an unmanned flight lasting 10 minutes. A hot air balloon for manned flight uses a single-layered, fabric gas bag (lifting "envelope"), with an opening at the bottom called the mouth or throat. Attached to the envelope is a basket, or gondola, for carrying the passengers. Mounted above the basket and centered in the mouth is the "burner", which injects a flame into the envelope, heating the air within. So what are you waiting for? Click start, jump aboard and put the yellow and red balloon back together to solve today's fun new jigsaw puzzle. Have fun!
