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?

Yes - Clement Ader in France

A heavier-than-air, powered, controlled, non-maneuvering level flight?

Yes - Clement Ader again

A heavier-than-air, powered, controlled, maneuvering, downhill flight?


Sir George Cayley designed several gliders and reportedly at least
one steam powered machine that were flown downhill by his coachman

Can any reccomend a good web page or book?


Google will get you lots
