Canberra, Hunter, Buccaneer, DC3, B747, Concorde all share a common phenomenon:
If it looks right, it is right.
I agree about this for all except the Buccaneer - in my opinion Blackburn were fundamentally incapable of turning out designs that "looked right", the Buccaneer looking as if it was designed by a committee who couldn't agree. The Beverley was another case, as Goudie points out above.
Yet their products apparently worked well enough, so it seems there have been honourable exceptions to that time-honoured "rule".
