Re: White Room Thursday Quiz 1 Aug 2019

Thanks @jezza1234 for your response:

 

I therefore challenge the adjudication of the answer joyjoyjoyjoyjoy and of course open this up to debate. All in the spirit of fun of course

 

This is welcomed - as the quiz is meant to be fun - and this is one subject around which there have been several claims and some controversy.

Taking into account the definition of aeroplane, Clement Ader of France patented his steam-powered avion [aeroplane] in April 1890, and it is claimed he flew his bat-shaped Eole, fitted with a 20hp steam engine, at Armainvilliers, Seine-et-Marie, France on 9 October 1890 - but the flight was not sustained nor controlled. It was also claimed that Ader flew his Avion III, fitted with two 20hp steam engines, 300m [984ft] at Satory, France on 12 and 14 October 1897 - but Charles Dollfus, curator at Musee de l`Air, [aris, having studied the evidence, concluded "Ader did not fly for a single instance at Satory during the tests of October 12 and 14, 1897".

Samuel Pierpont Langley, Secretary of Smithsonian Institute, built several steam-powered model aircraft in 1887 but all were failures. His rebuilt model No5 flew 3300ft on 6 May 1896. Charles Manley redesigned Langley`s plane, and a quarter-sized model, fitted with 52hp engine was tested in Jan 1902. A full-size plane, with Manley as pilot, took off from a houseboat on the Potomac river on 7 Oct 1903 but dropped into the river, and was repeated with the same result on 8 Dec 1903.

 

However, there was one person who made a sustained, controlled flight in a powered aeroplane before the Wright Brothers.

Gustave Weisskopt of Germany moved to America in the 1890s, changed his name to Whitehead, and began building model aircraft.

In 1901, Bridgeport Sunday Herald, Connecticut, USA reported Whitehead had made the first sustained controlled flight in a heavier-than-air, steam powered aeroplane, flying over half a mile on 14 August 1901.

In April 1902, American Inventor magazine reported Whitehead had flown his No21 Aeroplane two miles over Long Island Sound and had landed safely on water, and had made a second flight with a round distance of seven miles, again landing safely in the water - both on 17 January 1902. 

 

It is worth noting that Orville Wright, annoyed at the Smithsonian crediting Langley, sent the Flyer to the Science Museum, London. It was only sent to the American National Museum after it agreed it would never publish or display any statement claiming any aircraft earlier than the Wright Brothers` Flyer in 1903 was capable of carrying a man under its own power.
