Hot air balloon
An aircraft that rises by buoyancy after the air inside its envelope is heated to be lighter than the surrounding air; the Montgolfier brothers achieved the first manned flight in 1783.
The hot air balloon invented by the Montgolfier brothers in 1783 was made of hemp sacking and lifted by burning straw and wool. The only skills required were sewing and fire-making—technically possible since the Neolithic era.
