Article contains plenty of false information[edit]

- There is no "Siemens-FlyEco Magnus eFusion". The plane is called "Magnus eFusion". https://www.magnusaircraft.com/en/products/2
- Not clear whether this article is talking about the 'hybrid eFusion' or the 'eFusion'. Both use the same airframe (Magnus Fusion), but different propulsion systems. The article conflates both.
- The hybrid-electric never crashed. The article refers to a plane crash involving a fully electric aircraft, not a hybrid-electric one. http://www.kbsz.hu/j25/dokumentumok/2018-322-4%20Preliminary%20report%20ITM-KBSZ.pdf
- The article attributes design of the plane to Siemens and FlyEco. This is wrong as the design is by Magnus. https://www.siemens.com/press/en/feature/2015/corporate/2015-03-electromotor.php?content[]=Corp#event-toc-7
- Siemens designed the propulsion systems in both cases, there is no input from FlyEco for this beyond the provision of the combustion engine. https://www.siemens.com/press/en/feature/2015/corporate/2015-03-electromotor.php?content[]=Corp#event-toc-7
- The picture shown is the fully electric eFusion, not the hybrid - Picture of hybrid eFusion: https://www.aerokurier.de/general-aviation/aero/hybridantrieb-magnus-hybrid-mit-smart-diesel/752116
- The Manufacturer of the plane is not "Siemens and FlyEco" but "Magnus" https://www.magnusaircraft.com/en/products/2
- The fully electric shown had its first flight in April 2016 https://www.siemens.com/content/dam/internet/siemens-com/innovation/innovation/pdfs/press-release-siemens-magnus-english.pdf
- None of the Magnus eFusion planes are German. Magnus Aircraft is a Hungarian company and the planes are operated by Magnus with Hungarian licenses.
- "No cause of the accident has been determined" is incorrect. Pilot error has been established as the cause of the accident of the eFusion. http://www.kbsz.hu/j25/dokumentumok/2018-322-4%20Preliminary%20report%20ITM-KBSZ.pdf

Thanks for posting all the refs above. Obviously these refs contradict the cited refs, especially the Flight Global and AVweb refs in the article, so give me a bit of time to sort them all out. I will probably have some questions for you, since even a preliminary read of them doesn't entirely agree with what you have said above. - Ahunt (talk) 14:13, 10 January 2019 (UTC)[reply]
Okay I have read all the refs, the ones in the article and the ones you have noted above and I have to admit they all add up to some confusion.
  • The Magnus company website lists the following aircraft: Fusion UL, 212, 213, sFusion, all piston-powsered and the eFusion, which is all electric. It is described as being a joint "Magnus-Siemens" project. There is no listing for a hybrid version there that I found.
  • The first cited AVweb article deals just with the hybrid only and calls it a Siemens And FlyEco project.
  • The Flight Global article on the crash indicates it was an all-electric model and indicates it is a Magnus project with a powertrain by eAircraft at Siemens. This is consistent with the Magnus website.
  • The second cited AVweb article on the crash implies that the crashed aircraft was a hybrid and that "The aircraft was built in a collaboration between Siemens and Magnus Aircraft, and debuted at Aero Friedrichshafen in Germany in April this year." This seems to contradict or at least confuse with the Flight Global report
  • Your Hungarian accident report ref indicates the crashed aircraft was an all-electric eFusion, built by Magnus, but owned by Siemens and operated by Magnus. This preliminary report does not come up with a cause factor for the crash.
  • The Siemens project page you cited indicates that the hybrid is "This hybrid Magnus eFusion is equipped with a Siemens SP55D electric motor and a FlyEco Diesel engine" Siemens terms these projects a collaboration.
  • The Siemens press release just indicates the company developed an electric motor for aircraft use
  • The press release] mentions FlyEco as the provider of the diesel engine for the hybrid model
  • This AeroKurier article credits the hybrid to Magnus, using a Siemens electric motor and FlyEco diesel engine in the hybrid.
  • The Magnus product page for the eFusion in fact says "The Magnus-Siemens cooperation has given birth to the eFusion, the fully electric driven aircraft".
  • The press release by Siemens credits both companies for the development of the all-electric version, but does call it the Magnus eFusion.
  • Once again the Hungarian preliminary accident report does not draw any conclusions about the cause of the crash of the all-electric eFusion. It just rules out mechanical failure. So the cause of the accident is still yet to be determined.
All of this indicates that at least some of the sources, like AVweb, have confused the all-electric and the hybrid models. It was an all-electric model that crashed, not a hybrid as AVweb had reported. Magnus and Siemens both call the all-electric model the product of cooperation between the two companies, but name it as the Magnus eFusion. The hybrid version's name is not clear as Magnus does not have it listed as one of their products. Siemens calls it a "hybrid Magnus eFusion", but there is no clear nomenclature for it. It isn't clear at all who developed the hybrid model, whether it was a Magnus project using Siemens and FlyEco drive components or a Siemens project using an eFusion airframe. It is pretty clear that Fly Eco just provided the diesel, though. Did I miss anything here?- Ahunt (talk) 18:46, 10 January 2019 (UTC)[reply]
