History of Flight: Unpowered Flight

If you had to guess where would you say the first lighter-than-air craft was invented?

If you said China, you're either-well versed in history or you know how to game a short-answer test. Because, let's be honest here, the Chinese have invented 90% of everything. If you're ever on Jeopardy and the hint starts with, "The first place to invent…" Don't even read the rest of the question. Just buzz in and say, "What is China?"
  First in Flight CC Takeaway via Wikimedia CommonsFirst documented in the 3rd century CE, the sky lantern is a hot-air balloon with an envelope made of paper and a fire slung underneath. Its invention is usually credited to Zhuge Liang, a military strategist of the Three Kingdoms period, and to this day is also called by his courtesy name, Kongming. Originally used as a psychological weapon to spook the hell out of enemy troops,
Europe would not replicate this technology until 1709, when Bartolomeu de Gusmão flew a paper balloon of the same basic design as the Kongming lantern to a height of 12 feetAnd while we're on the subject, do you know where the first heavier-than-air craft was invented? Yeah, that was China, too. That aircraft is the kite, invented in China in the sixth century CE, if not earlierBut surely the first human being to fly was Orville Wright? Or, if not him, then Jean-François Pilâtre de Rozier, the first man to ascend in a tethered hot air balloon in 1783?
So, do you remember what I said earlier about buzzing in quickly if you're ever on Jeopardy? Yeah. The first documented human being to achieve flight was Yuan Huangtou, the son of a deposed Chinese emperor, in the 6th century CE. It wasn't as auspicious an event as you might be imagining, however. Guinness wasn't there, for one thing, and Yuan Huangtou was a prisoner of Gao Yang, a man who combined the traits of a scientific tinkerer with those of a true psychopath. Yuan Huangtou and other prisoners were tied to kites and thrown off the Tower of the Golden Phoenix in Ye. Alone among these unwilling pioneers of aeronautics, his kite actually flew, traveling a distance of two and a half kilometers before landing safelyThere are even stories of Lu Ban inventing a kite capable of lifting a man into the air as early as the 5th century BCE, for surveillance or as a platform for archery  Europe Discovers Finally Figures Out Flight
But whoever may have first invented the manned kite, credit for the first manned balloon goes to the Montgolfier brothers, Joseph and Etienne, of France. The Montgolfiers were paper manufacturers, because it just keep coming back to paper, doesn't it? Say, who was it that invented paper, again? I don't know, probably some white dude, right?
ANYWAY. The Montgolfiers got their start in the business of flight by experimenting with paper balloons and various buoyant substances. They first tried steam, but found that steam and a paper balloon don't go together super well. Then, learning of Henry Cavendish's experiments with hydrogen—then called "inflammable air"—they tried to fill their paper balloons with that. It didn't work, the hydrogen leaking out too quickly to provide buoyancy, but at least they didn't blow themselves up
Their breakthrough came in 1782, when Joseph noticed flecks of ash rising up a chimney. Believing that the smoke from the fire was permeated with a heretofore unknown type of buoyant gas, he named it Montgolfier GasIn a classic case of snobbery being the mother of invention, the French Academy was pissed that a couple of paper mongers had beaten them to a lighter-than-air balloon, and so commissioned Jacques Charles to duplicate the Montgolfier brothers' creation. Charles was confident of success, though it turned out he didn't have a clue how the brothers' balloon operated. He planned to buoy his own balloon with Cavendish's inflammable air, and lucky for him, paper was not a politically acceptable envelope material. Instead, he outsourced the job to brothers Marie-Noel and Anne-Jean Robert, who had developed a means of coating silk with rubber to make a tough material that retained hydrogen gas for long enough to loft a balloon.
It worked, and the test balloon ascended three thousand feet above Paris before drifting away and coming to a landing in the village of Gonesse. There, believing it had come from the devil, the villagers attacked the balloon with pitchforks, flails, and at least one firearm, before tying it to a horse and dragging it across the countrysideFrom Astra Castra: Experiments and Adventures in the Atmosphere
So, do I even need to point out that there are no recorded cases of Chinese villagers committing aggravated assault against a Kongming lantern? No? Okay then, let's move on.
The aerial competition between the Montgolfiers and Jacques Charles was now on. The Montgolfiers came back strong, lofting living passengers aboard a flying machine for the first time in European history in September of 1783. Those passengers were a sheep, a duck, and a rooster. In the presence of King Louis, they were sent up in a wicker basket slung under a balloon decorated with the royal arms. The animals came down intact from an estimated height about 1,700 feet, confirming that life could survive at the lofty altitude of… well, a smallish hill. Seriously though, some scientists doubted that  First Manned Flight (Subcategory: Voluntary)With those naysayers out of the way, the race was on to take a person into the air. Again, the Montgolfiers were first in Europe. That is, they were the first to build a balloon that could do it. They weren't the first to go up in it—are you crazy? They sent some snot-nosed kid up ahead of them, and so Jean-François Pilâtre de Rozier made the first tethered flight, less than a month after the concept was proven on a sheep
Another month saw another breakthrough from the Montgolfiers: sending not just one but two poor bastards up in a balloon, and cutting the cord. It was Rozier again, joined this time by Marquis François-Laurent d'Arlandes. The Marquis was a last minute substitution, by order of the king. Louis had actually wanted condemned criminals to be the first to make an untethered flight, but Rozier wasn't hearing it. He talked to the Marquis, who talked Louis out of robbing Rozier of his glory. Louis agreed, with one condition: that the Marquis accompany him. Because even kings have a sense of humor.
The aeronauts rode on a wicker balcony surrounding a brazier on the underside of the balloon. They carried a supply of straw, which they were supposed to steadily feed onto the fire, though the Marquis was distracted by the sights passing below and had to be continually reminded of his task. He was also somewhat distracted when the balloon caught fire. No bigs, though. He spotted it in time and put it out with a wet sponge. If he hadn't been quite so on the ball, they would have come down in a flaming wreck onto the rooftops of Paris.Late but not to be outdone, the Robert brothers replicated the feat ten days later, sending Nicolas-Louis Robert—the elder brother—and Jacques Charles up in a hydrogen balloon. With no need for a brazier, their balloon featured a boat-shaped gondola, beating the Montgolfiers on style by a wide margin. They also beat them on duration, staying up two hours where the first untethered flight of the Montgolfier balloon—depending as it did on a continuous supply of fuel to stay aloft—only lasted half an hour.
Ebullient at the achievement, Charles stayed aboard after they'd landed. Once the elder Robert disemballooned, he signaled the ground crew to let go and went back into the air. Which was rather poor judgement on his part, since he hadn't considered the reduction in ballast from his departing co-pilot. He shot up to 10,000 feet so quickly that he saw the sunset twice in one day: once from the ground and again from aloft, having risen to an altitude where it hadn't yet gone down. As cool as this may sound, I wouldn't try it at home. Charles certainly didn't recommend it. He described an excruciating pain in one ear, and vented hydrogen to bring himself back down  The Sky ConqueredAt the beginning of 1782, the lighter-than-air balloon was a festive tradition and niche tool of military signalling, so unknown in Europe that Joseph Montgolfier thought he'd discovered hot air and tried to name it after himself. By the end of 1782, a human being had gone to 10,000 feet and returned safely to Earth.

The years to come would see even greater feats. In 1784, the balloonist Jean-Pierre Blanchard flew a distance of 70 miles. In 1785, he crossed the English ChannelThe only question that remained was, "So, uh, how do we use this to kill each other?"
We'll see how it was answered in the next article.
