What was the primary experimental focus during the final, crucial phase involving the manned flight on November 21, 1783?
Answer
Creating an apparatus for the pilot to regulate the heat source safely within the basket
While the foundational lift mechanism was established through earlier tests, the final, definitive experimental phase concentrated on operational control and safety during human conveyance. Specifically, for the first untethered flight, meticulous attention was paid to developing the apparatus housed within the basket. This system had to allow the aeronaut, Pilâtre de Rozier, to safely manage the fire, which was fueled by burning straw and wood, to regulate the heat supply. This ability to control the ascent and descent via heat management was the essential component that validated the entire engineering endeavor for practical application.
