Now here’s an aircraft I hadn’t come across before: the Coléoptère.
It was a French VTOL plane designed in the late ’50s.
It made a few test flights, but crashed on one of them… it never went into production. [Clicking on the pictures will take you to more info.]
Thanks to Yann Le Cun, whose blog linked me to this diagram, which made me curious to find out more…
Er, shouldn’t it be Vertical Thinking? 🙂
