Fairey Mirage
Well, Mr. Driver of Sheep, Monsieur Dassault did remark that he just couldn't understand why the Powers That Be preferred the P1B/Lightning to the FD2, but I'm sure that his own teams didn't need outside help (apart from, perhpas, phots ... ???) when designing a versatile delta-winged fighter?
I think he regarded the Lightning as a "one-trick pony", but hjave no reson to say that he was right ...
(FWIW)
