Flight: From Dinosaurs to Space

  • Summary

  • Humans have probably considered flight since they found birds. As far as 228 million years ago, the Pterosaurs used flight to reign down onto other animals from above and eat them. The first known bird-like dinosaur was the Archaeopteryx, which lived around 150 million years ago. It’s not considered an ancestor of modern birds - but other dinosaurs from the same era, the theropods, are. 25 million years later, in modern China, the Confuciusornis sanctus had feathers and could have flown. The first humans wouldn’t emerge from Africa until 23 million years later. By the 2300s BCE, the Summerians depicted shepherds riding eagles, as humanity looked to the skies in our myths and legends. These were creatures, not vehicles. The first documented vehicle of flight was as far back as the 7th century BCE when the Rāmāyana told of the Pushpaka Vimāna, a palace made by Vishwakarma for Brahma, complete with chariots that flew the king Rama high into the atmosphere. The Odyssey was written around the same time and tells of the Greek pantheon of Gods but doesn’t reference flight as we think of it today. Modern interpretations might move floating islands to the sky, but it seems more likely that the floating island of Aeollia is really the islands off Aeolis, or Anatolia, which we might refer to as the modern land of Turkey.  Greek myths from a few hundred years later introduced more who were capable of flight. Icarus flew into the sun with wings that had been fashioned by Daedalus. By then, they could have been aware, through trade routes cut by Alexander and later rulers, of kites from China. The earliest attempts at flight trace their known origins to 500 BCE in China. Kites were, like most physical objects, heavier than air and could still be used to lift an object into flight. Some of those early records even mention the ability to lift humans off the ground with a kite. The principle used in kites was used later in the development of gliders and then when propulsion was added, modern aircraft. Any connection between any of these is conjecture as we can’t know how well the whisper net worked in those ages. Many legends are based on real events. The history of humanity is vast and many of our myths are handed down through the generations. The Greeks had far more advanced engineering capabilities than some of the societies that came after. They were still weary of what happened if they flew too close to the sun. In fact, emperors of China are reported to have forced some to leap from cliffs on a glider as a means of punishment. Perhaps that was where the fear of flight for some originated from. Chinese emperor Wang Mang used a scout with bird features to glide on a scouting mission around the same time as the Icarus myth might have been documented. Whether this knowledge informed the storytellers Ovid documented in his story of Icarus is lost to history, since he didn’t post it to Twitter. Once the Chinese took the string off the kite and they got large enough to fly with a human, they had also developed hang gliders. In the third century BCE, Chinese inventors added the concept of rotors for vertical flight  when they developed helicopter-style toys. Those were then used to frighten off enemies. Some of those evolved into the beautiful paper lanterns that fly when lit.There were plenty of other evolutions and false starts with flight after that. Abbas ibn Ferns also glided with feathers in the 9th century. A Benedictine monk did so again in the 11th century. Both were injured when they jumped out of towers in the Middle Ages that spanned the Muslim Golden Age to England.  Leonardo da Vinci studied flight for much of his life. His studies produced another human-power ornithopter and other contraptions; however he eventually realized that humans would not be able to fly on their own power alone. Others attempted the same old wings made of bird feathers, wings that flapped on the arms, wings tied to legs, different types of feathers, finding higher places to jump from, and anything they could think of. Many broke bones, which continued until we found ways to supplement human power to propel us into the air. Then a pair of brothers in the Ottoman Empire had some of the best luck. Hezarafen Ahmed Çelebi crossed the Bosphorus strait on a glider. That was 1633, and by then gunpowder already helped the Ottomans conquer Constantinople. That ended the last vestiges of ancient Roman influence along with the Byzantine empire as the conquerers renamed the city to Instanbul. That was the power of gunpowder. His brother then built a rocket using gunpowder and launched himself high in the air, before he glided back to the ground.  The next major step was the hot air balloon. The modern hot air balloon was built by the Montgolfier brothers in France and first ridden in 1783 and (Petrescu & Petrescu, 2013). 10 days later, the first gas balloon was invented by Nicholas Louis Robert and Jacques Alexander Charles. ...
