This picture was amusing to show
to people at a time where Mirage F1 was not very well known: a
number of them had troubles to decide what was the wing. About 40%
decided for the low surface. Explanation: viewed from the lens,
elevator was the first and had to be optically of greater span
than the wing, this being confirmed by the greater chord of the
low surface...A man, more technical, argued that the four sectors
actuated the mobile tailplane element and that it was normal that
the wing was cleaner and lower than the rear horizontal surface...
All would have been easier with landing gear in the wings. I provocate you a little: Are you sure the aircraft is not a top secret Mirage delta biplane with a weather vane at top???
