HEROIC GUYNEMER 100 YEARS AGO

Here is a tribute to Captain Georges GUYNEMER who was killed in action on September 11th, 1917. Three months earlier, he fought with Ernst Udet, the ace who came up 2nd after the Red Baron. You can watch hereafter how this dogfight reportedly happened, and how these fighter pilots had the gut to keep honor above all:

Remember Guynemer’s mottos:

FAIRE FACE (face up to it) was then adopted by the French Air Force Academy (FAFA) as their motto. A few words that well expresse the French pilots’ bravery.

WWI French ace Georges Guynemer used to say:

« Il y a une limite à toute chose, et il faut toujours la dépasser. »

‘Everything has a limit which has always got to be surpassed.’

« Lorsque l’on n’a pas tout donné, on n’a rien donné. »

‘As long as you have not given your all, you have given nothing.’

Loyal to these principles, the French ace took part in several hundreds of aerial combats, crediting 53 victories, maybe 88 victories because the French victory validation system was demanding. He was shot down seven times, and he was admired for he always survived, but that September 11, a hundred years ago. The hero took off once again, dashed to the frontlines, outnumbered by German warplanes in a last dogfighting over Belgium. Then, he fell. Since then, the French Air Force aviators have worn a black tie in sign of mourning.

WING LIFT THEORY SHAKEN – LA THÉORIE DE LA PORTANCE DE L’AILE ÉBRANLÉE

I had already written about that in my book UNE AUTRE HISTOIRE DE L’AVIATION, on pages 12; 13; 71; and others – Bernoulli’s principle does not explain everything. We know that aircraft fly. Strange as it may seem, Bernoulli’s principle has often been taught for decades as the explanation of the phenomenon.

Je l’avais déjà évoqué dans mon livre « Une autre histoire de l’aviation » aux pages 12, 13, 71, et d’autres: Le théorème de Bernoulli n’explique pas tout. Nous savons que les avions volent. Depuis des décennies, aussi bizarre que cela puisse paraître, on enseigne souvent le théorème de Bernoulli comme l’explication principale au phénomène.

This explanation would make sense if the air particles split at the leading edge of the wing and come together at the trailing edge. However, Cambridge researchers had debunked this flying myth in 2012, and have recently confirmed that Bernoulli’s principle cannot explain everything in wing lift. As you can see on the video above, the upper wing air stream travels much faster than the lower wing one. Last but not least, these air streams do not come together at the trailing edge since the upper wing air stream reaches the trailing edge well before the lower wing airflow. Isn’t this amazing?

Cette explication tiendrait si les particules d’air se séparaient au bord d’attaque de l’aile et se rejoignaient au bord de fuite. Cependant, des chercheurs de Cambridge avaient démonté ce mythe du vol en 2012 et viennent de confirmer que le principe de de Bernoulli ne peut pas tout expliquer dans la portance de l’aile. Comme vous pouvez le voir sur la vidéo ci-dessus, le flux d’air en extrados voyage beaucoup plus vite que celui d’intrados. Enfin et surtout, ces flux d’air ne se rejoignent pas au bord de fuite puisque le flux d’air d’extrados atteint le bord de fuite bien avant le flux d’intrados. Étonnant, n’est-ce pas?

LONDON AIRPORTS

Have you ever wondered how many Londonian airports have been built since the 1900s? Here is one of the best videos I have seen about this topic. It is one of a series produced by the comedian Jay Foreman. Thanks to this great source of information, you can have the answer as well as some fun.

Another interesting video tells us the train options to connect the six London airports to the City of London:

As you can see, it may cost an arm and a leg to travel to London. However, London airport system is the busiest one in the world. It demands a lot of concentration from its air traffic controllers as shown in this previous post: http://airforces.fr/2016/06/25/london-air-traffic-well-explained/

FLIGHT RADIOTELEPHONY VARIANTS

GREAT VIDEO – Watch for pleasure, first. Listen carefully to the figures and phrases uttered and compare with the various texts that are enforced in the world, and in Europe. In such an extreme situation, you may understand that the procedures are turned into a faster phraseology. So, why not adopt it in GAT (General Air Traffic), after all? 😉

SUPERBE VIDÉO: Regardez d’abord pour le plaisir. Écoutez attentivement les chiffres et expressions et comparez les avec les textes en vigueur dans le monde et en Europe. Dans une situation aussi extrême, on peut comprendre que les procédures se fassent plus rapidement dans la phraséologie. Alors pourquoi ne pas l’adopter dans la CAG (Circulation Aérienne Générale), après tout? 😉

GUSTAVE WHITEHEAD FLEW ON AUGUST 14, 1901

He took off that day. It was 115 years ago, two years before the Wrights. Gustav Weisskopf had changed his name into Gustave Whitehead before building his aeroplane whose name was the « Condor », or number 21. Gustave was a German immigrant from Leutershausen in Bavaria, where a splendid museum https://www.weisskopf.de commemorates the feats of the brilliant inventor.

Two replicas of his plane #21 flew in 1986 in the U.S.A., and in 1997 in Germany. Several books have been written about Gustave Whitehead so far. Susan O’Dwyer Brinchman published the latest one last year. Her searching follows her father’s, Major William J. O’Dwyer, a retired U.S. Air Force Reserve officer who had found early Whitehead’s photos in an attic, in 1963, and researched Whitehead for the next 45 years, interviewing many witnesses. Susan worked with him during the later decades and recently, has found even more. She explains why Whitehead must have been the first in the world to perform a steerable, propelled without catapult, heavier-than-air flight. She shares an extensive FAQ and lots of resources on her website here: http://gustavewhitehead.info/gustave-whitehead-resources/  which are quite compelling. You can order her book Gustave Whitehead: First in Flight on Amazon or get a signed one by clicking on the cover here below:
