Richard Holmes - Falling Upwards

Baldwin also notices how the balloon responded to air currents arising from the earth beneath. His careful flight-mapping shows how it was constantly drawn downwards to follow the cool, curving airflows above the meanderings of the river. Similarly, the heady act of leaning directly over the side of the basket to paint, observe and measure makes him sensitive to shifts in shade and colour and perspective on the ground below.

One typical observation reads: ‘The river Dee appeared of a red colour; the city [Chester] very diminutive; and the town [Warrington] entirely blue. The whole appeared a perfect plane, the highest buildings having no apparent height, but reduced all to the same level, and the whole terrestrial prospect appeared like a coloured map.’ 13

Baldwin also writes wonderfully well about clouds, and the prismatic effects of light. He clearly perceives a whole new world opening out around him, and expresses a euphoric emotional reaction. Indeed, to keep these feelings within bounds, he writes of himself throughout his flight in the third person: ‘A Tear of pure Delight flashed in his Eye! of pure and exquisite Delight and Rapture!’ For him, ballooning instinctively combined both scientific discovery and aesthetic pleasure. But perhaps it should provide more? He could imagine the time when ‘aerostatic ships make the Circuit of the Globe’. 14

The essential mystery of ballooning – the enigmatic meaning of the original dream – was there from the start. Almost a decade after its invention by the Montgolfier brothers, with flights recorded in many nations, including Germany, Italy, Russia and America, it was still not clear, either to the Royal Society in London or the Academy of Sciences in Paris, what the true purpose or possibilities of ballooning really were. Don Paolo Andreani had flown from Milan in February 1784; Jean-Pierre Blanchard and Dr John Jeffries had traversed the Channel in January 1785; Pilâtre de Rozier had died attempting the same crossing in the opposite direction with a composite hydrogen and hot-air balloon in June 1785 (thereby becoming the first scientific balloon martyr); Baron Lütgendorf had ‘partially’ flown at Augsburg in August 1786; and Blanchard had gone on to demonstrate ballooning in virtually every major city in Europe, finally crowning his international career with what he claimed was the first ever American ascent, from the city of Philadelphia in January 1793, carrying an ‘aerial passport’ endorsed by President George Washington, and successfully crossing the Delaware river into New Jersey. 15

Yet all these ascents were essentially public spectacles and entertainments. ‘Flight’ itself remained a novel and surprisingly unexplored concept. What, in practice, could balloons actually do for mankind, except provide a hazardous journey interspersed with the fine aerial ‘Prospects’ that men like Dr Charles and Thomas Baldwin recorded so eloquently?

According to Barthélemy Faujas de Saint-Fond, the Parisian promoter of the Montgolfier balloons, they might, for example, provide observation platforms: for military reconnaissance, for sailors at sea, for chemists analysing the earth’s upper atmosphere, or for astronomers with their telescopes. It is notable that most of these applications were based on the notion of a tethered balloon. In fact many of the Montgolfiers’ early experiments were made with tethered aerostats, held to the ground by various ingenious forms of harness, guy ropes or winches. fn5

The poet and inventor Erasmus Darwin’s first practical idea of balloon power was, paradoxically, that of shifting payloads along the ground. He suggested to his friend Richard Edgeworth that a small hydrogen balloon might be tethered to an adapted garden wheelbarrow, and used for transporting heavy loads of manure up the steep hills of his Irish estate. This convenient aerial skip would allow one man to shift ten times his normal weight in earth, but also in bricks or wood or stones. In fact it might cause a revolution in the entire conditions of manual labour. 17

Similarly, Joseph Banks, the President of the Royal Society, had the initial idea that balloons could increase the effectiveness of earthbound transport, by adding to its conventional horsepower. He saw the balloon as ‘a counterpoise to Absolute Gravity’ – that is, as a flotation device to be attached to traditional forms of coach or cart, making them lighter and easier to move over the ground. So ‘a broad-wheeled wagon’, normally requiring eight horses to pull it, might only need two with a Montgolfier attached. This aptly suggests how difficult it was, even for a trained scientific mind like Banks’s, to imagine the true possibilities of flight in these early days. 18

Benjamin Franklin, ‘the old fox’, as Banks’s secretary Charles Blagden called him, was quick to suggest various menacing military applications, perhaps in a deliberate attempt to fix Banks’s attention. ‘Five thousand balloons capable of raising two men each’ could easily transport an effective invasion army of ten thousand marines across the Channel, in the course of a single morning. The only question, Franklin implied, was which direction would the wind be blowing from? 19

His other speculations were more light-hearted. What about a ‘running Footman’? Such a man might be suspended under a small hydrogen balloon, so his body weight was reduced to ‘perhaps 8 or 10 Pounds’, and so made capable of running in a straight line in leaps and bounds ‘across Countries as fast as the Wind, and over Hedges, Ditches & even Water …’ Or there was the balloon ‘Elbow Chair’, placed in a beauty spot, and winching the picturesque spectator ‘a Mile high for a Guinea’ to see the view.

There was also Franklin’s patent balloon icebox: ‘People will keep such Globes anchored in the Air, to which by Pullies they may draw up Game to be preserved in the Cool, & Water to be frozen when Ice is wanted.’ 20This contraption would surely have appealed to the twentieth-century illustrator W. Heath Robinson.

Franklin, who suffered formidably from gout, later suggested that a balloon might even be used to power a wheelchair. When he had returned from Paris to Philadelphia in autumn 1785, he began using a sedan chair lifted by four stout assistants for his daily commute from his house to the Philadelphia State Assembly Rooms. He suggested reducing the requisite manpower by 75 per cent, simply by harnessing the chair to a small hydrogen balloon, ‘sufficiently large to raise me from the ground’. This would make his malady less vexatious for all concerned, by providing a ‘most easy carriage’, lightweight and highly manoeuvrable, ‘being led by a string held by one man walking on the ground’. 21 fn6

In 1785 Tiberius Cavallo, a Fellow of the Royal Society, put together the first British study of ballooning. His A Treatise on the History and Practice of Aerostation studiously adopted the French scientific term for ‘lighter-than-air’ flight, but moved far beyond national rivalries. He wanted to consider the phenomenon of flight from both a scientific and a philosophical point of view. He thought that ballooning held out immense possibilities, less as a transport device than as an instrument for studying the upper air and the nature of weather. This distinction between horizontal and vertical travel would have a long subsequent history.
