I am absolutely not going to write "on another planet" in the title, but that's what I mean.
I found a cross-over point from here when I recently linked to my answer in space exploration stackexchange.
There are several questions about solar powered aircraft here, but in Earth's atmosphere. The expertise is here to ask flight-specific questions about the solar powered aircraft discussed for Venus Take a moment to look at Venus Aircraft - design evolution 2000-2008, Geoffrey A. Landis, NASA John Glenn Research Center) - is there any room for a discussion of the possibility of something like that being on-topic here?
I'm not going to post the question yet, but this is where people who know about atmospheric flight can be found, so I thought I would test the water.
