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
