The myth arises from: “If it were not for the clumsy way (UK) tackle things, you could have made (it.)” attributed to M.D in J.Gee,Mirage,MacDonald,1971 alluding to FD.2's visit to Cazeau, leaving 2 days before rollout of 1st. Mirage III. That design derived not from Fairey, but dumpy M.D.550 inspired by Lippisch in Germany, appraised by NACA/US, ONÉRA/France, RAE, “owned” by none.
