Today in History - 1783

French physician Jean-François Pilatre de Rozier and François Laurent, the marquis d' Arlandes, make the first untethered hot-air balloon flight, flying 5.5 miles over Paris in about 25 minutes. Their cloth balloon was crafted by French papermaking brothers Jacques-Étienne and Joseph-Michel Montgolfier, inventors of the world's first successful hot-air balloons.
