message: Since at least 2009 the article has stated that "the annular wing dates to Terry in 1964 / the boxplane was first proposed by Miranda in 1972". Who is Terry? Who is Miranda? -Ashley Pomeroy (talk) 00:04, 7 May 2011 (UTC)

message: Under "Characteristics", the sentence beginning "However any claimed aerodynamic advantages are illusory - -" seems to be intended convey the idea from Kroo's VKI paper that the performance of an open system can closely approach that of the closed system with the lowest possible drag, something that isn't obvious from looking at the lift distributions of the different systems, but is nonetheless true, largely due to the fact that the optimum lift distribution on a closed lifting system isn't unique.  But to my mind this idea doesn't come across at all in the current version, especially the non-uniqueness part, and I'm going to suggest a re-write.
The next sentence refers to "the downsides of being a fully closed system".  I don't see where Kroo identified any "downsides" to speak of, other than a lack of any significant fundamental advantage over open systems.  So I'll suggest rewording this too.
It also seems to me that the current version's discussion under "C-wing" isn't adequate to get the key ideas across, especially the relationship of the results in the accompanying graphic to the non-uniqueness issue I raised above, a relationship ref 20 calls attention to.  So I think this section also needs a re-write.
I have drafted my suggested changes in my sandbox.   Comments, anyone?J Doug McLean (talk) 23:58, 11 August 2018 (UTC)
replies: text: Hi Doug, welcome back. I would say, go to it. Copy your updated version live here. Few editors seem to pay much attention to this article, so your expertise is appreciated. I may make some edits to it, to make it more like a general encyclopaedia and less like a textbook, which I hope is OK by you, but I will try not to change any of your substance - or if I spot anything I will raise it on this talk page first. — Cheers, Steelpillow (Talk) 02:58, 12 August 2018 (UTC)
replies: text: Just to clarify one point. I see you have been asked at Talk:Lift (force) to draft any major edits in your sandbox first. However the article here does not have a history of significant contention, therefore there is no need to worry about such precautions here. — Cheers, Steelpillow (Talk) 16:02, 12 August 2018 (UTC)
