The Conquest of Air

Everybody in the USA, and in fact just about everyone across the world, has heard of Orville and Wilbur Wright. Two of the pioneers of aviation, when their experimental biplane Flyer achieved the first ever manned, powered, heavier-than-air flight on the morning of December 17, 1903, they had finally achieved one of man’s long-held dreams; control and mastery of air travel.

However, what is often puzzling when considering the Wright brothers’ story is the number of misconceptions surrounding them. Many, for instance, are under the impression that they were the first people to fly at all, inventing all the various technicalities of lift, aerofoil structures and control that are now commonplace in today’s aircraft. In fact, the story of flight, perhaps the oldest and maddest of human ambitions, an idea inspired by every time someone has looked up in wonder at the graceful flight of a bird, is a good deal older than either of them.

Our story begins, as does nearly all technological innovation, in imperial China, around 300 BC (the Greek scholar Archytas had admittedly made a model wooden pigeon ‘fly’ some 100 years previously, but nobody is sure exactly how he managed it). The Chinese’s first contribution was the invention of the kite, an innovation that would be insignificant if it wasn’t for whichever nutter decided to build one big enough to fly in. However, being strapped inside a giant kite and sent hurtling skywards not only took some balls, but was heavily dependent on wind conditions, heinously dangerous and dubiously useful, so in the end the Chinese gave up on manned flight and turned instead to unmanned ballooning, which they used for both military signalling and ceremonial purposes. It isn’t actually known if they ever successfully put a man into the air using a kite, but they almost certainly gave it a go. The Chinese did have one further attempt, this time at inventing the rocket engine, some years later, in which a young and presumably mental man theorised that if you strapped enough fireworks to a chair then they would send the chair and its occupants hurtling into the night sky. His prototype (predictably) exploded, and it wasn’t for two millennia, after the passage of classical civilisation, the Dark Ages and the Renaissance, that anyone tried flight again.

That is not to say that the idea didn’t stick around. The science was, admittedly beyond most people, but as early as 1500 Leonardo da Vinci, after close examination of bird wings, had successfully deduced the principle of lift and made several sketches showing designs for a manned glider. The design was never tested, and not fully rediscovered for many hundreds of years after his death (Da Vinci was not only a controversial figure and far ahead of his time, but wrote his notebooks in a code that it took centuries to decipher), but modern-day experiments have shown that his design would probably have worked. Da Vinci also put forward the popular idea of ornithopters, aircraft powered by flapping motion as in bird wings, and many subsequent attempts at flight attempted to emulate this method of motion. Needless to say, these all failed (not least because very few of the inventors concerned actually understood aerodynamics).

In fact, it wasn’t until the late 18th century that anyone started to really make any headway in the pursuit of flight. In 1783, a Parisian physics professor, Jacques Charles, built on the work of several Englishmen concerning the newly discovered hydrogen gas and the properties and behaviour of gases themselves. Theorising that, since hydrogen was less dense than air, it should follow Archimedes’ principle of buoyancy and rise, thus enabling it to lift a balloon, he launched the world’s first hydrogen balloon from the Champs du Mars on August 27th. The balloon was only small, and there were significant difficulties encountered in building it, but in the design process Charles, aided by his engineers the Roberts brothers, invented a method of treating silk to make it airtight, spelling the way for future pioneers of aviation. Whilst Charles made some significant headway in the launch of ever-larger hydrogen balloons, he was beaten to the next significant milestones by the Montgolfier brothers, Joseph-Michel and Jacques-Etienne. In that same year, their far simpler hot-air balloon designs not only put the first living things (a sheep, rooster and duck) into the atmosphere, but, just a month later, a human too- Jacques-Etienne was the first European, and probably the first human, ever to fly.

After that, balloon technology took off rapidly (no pun intended). The French rapidly became masters of the air, being the first to cross the English Channel and creators of the first steerable and powered balloon flights. Finally settling on Charles’ hydrogen balloons as a preferable method of flight, blimps and airships began, over the next century or so, to become an accepted method of travel, and would remain so right up until the Hindenburg disaster of 1937, which rather put people off the idea. For some scientists and engineers, humankind had made it- we could now fly, could control where we were going at least partially independent of the elements, and any attempt to do so with a heavier-than-air machine was both a waste of time and money, the preserve of dreamers. Nonetheless, to change the world, you sometimes have to dream big, and that was where Sir George Cayley came in.

Cayley was an aristocratic Yorkshireman, a skilled engineer and inventor, and a magnanimous, generous man- he offered all of his inventions for the public good and expected no payment for them. He dabbled in a number of fields, including seatbelts, lifeboats, caterpillar tracks, prosthetics, ballistics and railway signalling. In his development of flight, he even reinvented the wheel- he developed the idea of holding a wheel in place using thin metal spokes under tension rather than solid ones under compression, in an effort to make the wheels lighter, and is thus responsible for making all modern bicycles practical to use. However, he is most famous for being the first man ever, in 1853, to put somebody into the air using a heavier-than-air glider (although Cayley may have put a ten-year old in a biplane four years earlier).

The man in question was Cayley’s chauffeur (or butler- historical sources differ widely), who was (perhaps understandably) so hesitant to go in his boss’ mental contraption that he handed in his notice upon landing after his flight across Brompton Dale, stating  as his reason that ‘I was hired to drive, not fly’. Nonetheless, Cayley had shown that the impossible could be done- man could fly using just wings and wheels. He had also designed the aerofoil from scratch, identified the forces of thrust, lift, weight and drag that control an aircraft’s movements, and paved the way for the true pioneer of ‘heavy’ flight- Otto Lilienthal.

Lilienthal (aka ‘The Glider King’) was another engineer, making 25 patents in his life, including a revolutionary new engine design. But his fame comes from a world without engines- the world of the sky, with which he was obsessed. He was just a boy when he first strapped wings to his arms in an effort to fly (which obviously failed completely), and later published works detailing the physics of bird flight. It wasn’t until 1891, aged 43, once his career and financial position was stable and he had finished fighting in the Franco-Prussian War, that he began to fly in earnest, building around 12 gliders over a 5-year period (of which 6 still survive). It might have taken him a while, but once he started there was no stopping him, as he made over 2000 flights in just 5 years (averaging more than one every day). During this time he was only able to rack up 5 hours of flight time (meaning his average flight time was just 9 seconds), but his contribution to his field was enormous. He was the first to be able to control and manoeuvre his machines by varying his position and weight distribution, a factor whose importance he realised was absolutely paramount, and also recognised that a proper understanding of how to achieve powered flight (a pursuit that had been proceeding largely unsuccessfully for the past 50 years) could not be achieved without a basis in unpowered glider flight, in recognising that one must work in harmony with aerodynamic forces. Tragically, one of Lilienthal’s gliders crashed in 1896, and he died after two days in hospital. But his work lived on, and the story of his exploits and his death reached across the world, including to a pair of brothers living in Dayton, Ohio, USA, by the name of Wright. Together, the Wright brothers made huge innovations- they redesigned the aerofoil more efficiently, revolutionised aircraft control using wing warping technology (another idea possibly invented by da Vinci), conducted hours of testing in their own wind tunnel, built dozens of test gliders and brought together the work of Cayley, Lilienthal, da Vinci and a host of other, mostly sadly dead, pioneers of the air.  The Wright brothers are undoubtedly the conquerors of the air, being the first to show that man need not be constrained by either gravity or wind, but can use the air as a medium of travel unlike any other. But the credit is not theirs- it is a credit shared between all those who have lived and died in pursuit of the dream of fling like birds. To quote Lilienthal’s dying words, as he lay crippled by mortal injuries from his crash, ‘Sacrifices must be made’.


Fitting in

This is my third post in this little mini-series on the subject of sex & sexuality in general, and this time I would like to focus on the place that sex has in our society. I mean, on the face of it, we as a culture appear to be genuinely embarrassed by its existence a lot of the time, rarely being referred to explicitly if at all (at least certainly not among ‘correct’ and polite company), and making any mention of it a cause of scandal and embarrassment. Indeed, an entire subset of language has seemed to develop over the last few years to try and enable us to talk about sexually-related things without ever actually making explicit references to it- it’s an entire area where you just don’t go in conversation. It’s almost as if polite society has the mental age of a 13 year old in this regard, and is genuinely embarrassed as to its existence.

Compare this to the societal structure of one of our closest relatives, the ‘pygmy great ape’ called the bonobo. Bonobos adopt a matriarchal (female-led) society, are entirely bisexual, and for them sex is a huge part of their social system. If a pair of bonobos are confronted with any new and unusual situation, be it merely the introduction of a cardboard box, their immediate response will be to briefly start having sex with one another almost to act as an icebreaker, before they go and investigate whatever it was that excited them. Compared to bonobos, humans appear to be acting like a bunch of nuns.

And this we must contrast against the fact that sex is something that we are not only designed for but that we actively seek and enjoy. Sigmund Freud is famous for claiming that most of human behaviour can be put down to the desire for sex, and as I have explained in previous place, it makes evolutionary sense for us to both enjoy sex and seek it wherever we can. It’s a fact of life, something very few of us would be comfortable to do without, and something our children are going to have to come to terms with eventually- yet it’s something that culture seems determined to brush under the carpet, and that children are continually kept away from for as long as is physically possible in a last-ditch attempt to protect whatever innocence they have left. So why is this?

Part of the reasoning behind this would be the connection between sex and nakedness, as well as the connection to privacy. Human beings do not, obviously, have thick fur to protect themselves or keep them warm (nobody knows exactly why we lost ours, but it’s probably to do with helping to regulate temperature, which we humans do very well), and as such clothes are a great advantage to us. They can shade us when its warm and allow for more efficient cooling, protect us from harsh dust, wind & weather, keep us warm when we venture into the world’s colder climates, help stem blood flow and lessen the effect of injuries, protect us against attack from predators or one another, help keep us a little cleaner and replace elaborate fur & feathers for all manner of ceremonial rituals. However, they also carry a great psychological value, placing a barrier between our bodies and the rest of the world, and thus giving us a sense of personal privacy about our own bodies. Of particular interest to our privacy are those areas most commonly covered, including (among other things), the genital areas, which must be exposed for sexual activity. This turns sex into a private, personal act in our collective psyche, something to be shared only between the partners involved, and making any exploration of it seem like an invasion of our personal privacy. In effect, then, it would seem the Bible got it the wrong way around- it was clothes that gave us the knowledge and shame of nakedness, and thus the ‘shame’ of sex.

Then we must consider the social importance of sex & its consequences in our society generally. For centuries the entire governmental structure of most of the world was based around who was whose son, who was married to who  and, in various roundabout ways, who either had, was having, or could in the future be having, sex with whom. Even nowadays the due process of law usually means inheritance by either next of kin, spouse or partner, and so the consequences of sex carry immense weight. Even in the modern world, with the invention of contraceptives and abortion and the increasing prevalence of ‘casual sex’, sex itself carries immense societal weight, often determining how you are judged by your peers, your ‘history’ among them and your general social standing. To quote a favourite song of a friend of mine: ‘The whole damn world is just as obsessed/ With who’s the best dressed and who’s having sex’. And so, sex becomes this huge social thing, its pursuit full of little rules and nuances, all about who with who (and even with the where & how among some social groups) and it is simply not allowed to become ‘just this thing everyone does’ like it is with the bonobos. Thus, everything associated with sex & sexuality becomes highly strung and almost political in nature, making it a semi-taboo to talk about for fear of offending someone.

Finally, we must consider the development of the ‘sexual subculture’ that seems to run completely counter to this taboo attitude. For most of human history we have comfortably accepted and even encouraged the existence of brothels and prostitution, and whilst this has become very much frowned upon in today’s culture the position has been filled by strip clubs, lap dancing bars and the sheer mountains of pornography that fill the half-hidden corners of newsagents, small ads and the internet. This is almost a reaction to the rather more prim aloofness adopted by polite society, an acknowledgement and embracing of our enjoyment of sex (albeit one that caters almost exclusively to heterosexual men and has a dubious record for both women’s and, in places, human rights). But because this is almost a direct response to the attitudes of polite culture, it has naturally attracted connotations of being seedy and not respectable. Hundreds of men may visit strip clubs every night, but that doesn’t make it an OK career move for a prominent judge to be photographed walking out of one. Thus, as this sex-obsessed underworld has come into being on the wrong side of the public eye, so sex itself has attracted the same negative connotations, the same sense of lacking in respectability, among the ‘proper’ echelons of society, and has gone even more into the realms of ‘Do Not Discuss’.

But, you might say, sex appears to be getting even more prevalent in the modern age. You’ve mentioned internet porn, but what about the sexualisation of the media, the creation and use of sex symbols, the targeting of sexual content at a steadily younger audience? Good question, and one I’ll give a shot at answering next time…
