My vector drawing (no auto trace/copy) of a de Vinci illustration, of a man powered aircraft in flight on a public domain background (publicdomainimages) of sunrise.
Most people with any knowledge or interest in early attempts at human-powered flight are familiar with the works of Leonardo Da Vinci and His Flying Machines, the famous fifteenth century renaissance artist and inventor. The question arises though, did the Da Vinci machines actually work, that is, fly successfully approximately four-hundred years before anybody else was able to accomplish the task? That is a question that has been debated for decades. There is no clear hard-core evidence that specifically states yes, however, if one goes over the material by Leonardo and his contemporaries one can cull out some rather interesting facts that attest to the fact that YES his machines did work and Leonardo did fly.
