Looking again, I am sure Skytrain is right and Graeme misunderstood what I meant by 'target', which is my fault for being too lazy to write 'aircraft we are looking for'.
It is a single seater so cannot be the V-11 and so is still a valid challenge, unkless I am wrong yet again
Therefore I think the silhouetted aircraft is the Vought V-143/V-150
I am starting to believe that I am retarded.
