Question: What is the connection between Félix du Temple de la Croix and Early flying machines?
Context: Col du Glandon (1924 m ) is a high mountain pass in the Dauphiné Alps in Savoie, France, linking Le Bourg-d'Oisans to La Chambre.  It is situated between the Belledonne, Grandes Rousses and Arvan-Villards mountain ranges, west of the Col de la Croix de Fer.  The road over the Col du Glandon was opened in 1898, although it was not linked to the Col de la Croix de Fer until 1912. Les Sept Paroles du Christ sur la Croix (composed 1859) is a musical setting of The Seven Last Words of Christ by César Franck, though the name in French often refers to an equally well or better known homonymous work by Charles Gounod "Les sept paroles de N.S. Jesus-Christ sur la croix". La Croix Fry is a small village contained within the Domaine de Manigod.  With a population of under 600 people La Croix Fry is a popular site for hill walking on the Plateau de Beauregard as well as skiing in the winter. Trois sonneries de la Rose+Croix ("Three Sonneries of the Rose+Cross") is a piano composition by Erik Satie, first published in 1892, while he was composer and chapel-master of the Rosicrucian "Ordre de la Rose-Croix Catholique, du Temple et du Graal ", led by Sâr Joséphin Péladan. The Théâtre de la Gaîté, a former Parisian theatre company, was founded in 1759 on the boulevard du Temple by the celebrated Parisian fair-grounds showman Jean-Baptiste Nicolet as the Théâtre de Nicolet, ou des Grands Danseurs.  The company was invited to perform for the royal court of Louis XV in 1772 and thereafter took the name of Grands-Danseurs du Roi.  However, with the fall of the monarchy and the founding of the First French Republic in 1792, the name was changed to the less politically risky Théâtre de la Gaîté.  The company's theatre on the boulevard du Temple was replaced in 1764 and 1808, and again in 1835 due to a fire.  As a result of Haussmann's renovation of Paris, the company relocated to a new theatre on the rue Papin in 1862, and the 1835 theatre (pictured) was subsequently demolished. Charles Eugène Gabriel de La Croix de Castries, marquis de Castries, baron des États de Languedoc, comte de Charlus, baron de Castelnau et de Montjouvent, seigneur de Puylaurens et de Lézignan (25 February 1727, Paris – 11 January 1801, Wolfenbüttel) was a French marshal.  He was the son of Joseph François de La Croix de Castries, marquis de Castries, and his second wife, Marie-Françoise de Lévis de Charlus. Félix du Temple de la Croix (18 July 1823 – 4 November 1890) (usually simply called Félix du Temple) was a French naval officer and an inventor, born into an ancient Normandy family.  He developed some of the first flying machines and is credited with the first successful flight of a powered aircraft of any sort, a powered model plane, in 1857, and is sometimes credited with the first manned powered flight in history onboard his Monoplane in 1874, The Col de la Croix Fry (1467 m ) is a mountain pass located in the Chaîne des Aravis, between Manigod and La Clusaz in the Haute-Savoie department of France.  The road over the col is used occasionally by the Tour de France cycle race with the tour crossing the pass on Stage 19 of the 2013 Tour.  At the summit is the village of La Croix Fry. The du Temple Monoplane was a large aeroplane made of aluminium, built in Brest, France, by naval officer Félix du Temple in 1874. Early flying machines include all forms of aircraft studied or constructed before the development of the modern aeroplane by 1910.  The story of modern flight begins more than a century before the first successful manned aeroplane, and the earliest aircraft thousands of years before.
