What was the principal scientific justification for including the sheep as a passenger in the wicker basket?
Answer
It was intended as a stand-in for a human being to judge physiological effects.
The sheep was considered the most crucial passenger because it was viewed as the best available proxy for assessing the impact of altitude changes, thinning air, and pressure fluctuations on the human body. Being a mammal of similar structure and mass to an average man, its survival and condition post-flight provided the essential, rudimentary biological proof of concept required before the Montgolfiers or anyone else could risk human life. This pragmatic substitution highlights the empirical, trial-and-error nature of 18th-century biomedical testing in aviation.
