People continued to attempt flight but eventually learned floating. The first manned balloon flight in history was made in France in 1783. The hot air balloon used heat from a fire at the base to raise the balloon into the sky. These balloons were used for observational purposes, and France even made a special "balloon unit." The use of balloons continued into the Civil War, helping to give a bird's eye view of the enemy. The observational power of being above ground was realized, although the capabilities remained limited due to difficulties controlling the balloons.
"Those [Civil War era U.S.] balloons were very limited in their deployment capability. In other words, they're gonna go where the wind goes, and so balloon observation was certainly a beginning, but it was a small step."
