A lot of people thought airplanes were impossible. And the way hummingbirds fly violate every law of physics.
the first statement is true, but since there were people all over the world working on airplanes, the RIGHT people didn't. Those "right" people included scientist and engineers. Powered flight was not considered an impossibility, it was simply difficult given the current power to weight ratio of engines at the time. Heck, BIRDS could fly, that is powered flight, nothing impossible about that.
Hummingbirds do NOT violate ANY law of physics. That is simply, factually, incorrect.
