Edoardo Jenner faceva esperimenti con l'aerostato!

[Valerio Ricciardi]

*Forse* per una volta mi riuscirà di far scoprire a Tartan qualcosa che ancora non sa su palloni aerostatici, mongolfiere ed aeronauti (si chiamano così, mi pare, i tipi buffi come lui che si divertono a stare appesi al cielo in un grosso cesto?)

Bé, leggete questo (se qualcuno di voi non traduce l'inglese, ve lo posso postare in ungherese che come noto è molto più alla portata di tutti)... parliamo proprio di Edward Jenner, il moderno re-introduttore della vaccinazione in occidente, che mise a punto il primo protocollo moderno di vaccinazione contro il vaiolo.

The Balloonist
The First Air BalloonsThe story of flight began at the end of 1782 near Lyons in France, when two brothers, Joseph and Etienne Montgolfier began experimenting with balloons.
They harnessed the power of wood smoke to lift objects from the ground. Jacques Charles launched the first balloon to use hydrogen as a lifting agent in Paris in August 1783. It was twelve feet in diameter, rose to a height of 3000 feet and travelled 15 miles.
Intense enthusiasm for anything concerned with balloons or ballooning followed the first manned flight in a Montgolfier balloon which took place from Paris in November 1783. In Britain the first unmanned balloon flight was probably one that took place in London in November 1783.

Caleb Hillier Parry launches a Balloon in BathEdward Jenner's lifelong friend, the physician Caleb Hillier Parry, probably carried out the first flight of an unmanned balloon in the Westcountry.
He launched a hydrogen balloon from the Crescent in Bath on 10th January 1784. It was 17ft in diameter and 8.5ft high, made of varnished silk. It flew 19 miles, landing just west of Wells.

Jenner's Hydrogen Balloon
Determined to try the experiment for himself, Edward Jenner wrote to Parry requesting a length of silk and urging him to join him in Berkeley.
Jenner launched his hydrogen balloon from the courtyard of Berkeley Castle at 2pm on 2nd September 1784. It flew 10 miles north eastwards, landing in a field at Kingscote, where, the Gloucester Journal reported, it terrified the reapers so much that for some time they could not be persuaded to approach it!
The balloon was re-launched and drifted north along the line of the hills for a further 14 miles. Its journey ended a few miles east of Gloucester at the beauty spot known as Birdlip. The local inn, known since the 1820s as the Balloon Inn and now called the Air Balloon Inn, may well commemorate this exciting event.
