Each time I see the list of qualifiers on the Wright Brothers flight,
I want to find the list of previous "flights"

Did someone make a heavier-than-air, powered, uncontrolled level flight?
A heavier-than-air, powered, controlled, non-maneuvering level flight?
A heavier-than-air, powered, controlled, maneuvering, downhill flight?

Can any reccomend a good web page or book?

just curious


Google search "John Stringfellow"
Powered heavier-than-air model in 1848, but didn't have the 'control'
requirement figured out. Worked OK in a controlled indoor environment
but he failed to appreciate the need for a vertical stabilizer.
