History of Flight/Lighter than air
Two French brothers by the names of Joseph-Michel and Jacques-Étienne Montgolfier came up with the idea of an air balloon. They made a big bag out of silk and blew hot air into the bag. The silk bag then was attached to a basket. Under the basket was smoke from the fire which helped the air to go to the silk bag and allow the balloon to rise.
The very first passengers by the balloon were three animals. The honor goes to a duck, rooster, and a sheep. They flew over one mile in a 6000 feet high altitude.
