Point of order, the F102 had quite ugly fairings (I believe they were called Marilyns for some reason
) scabbed onto the rear fuselage to achieve area rule, work was led by Whitcombe, which was my original point.
The F106 was a redesign of the original F102 (itself a redesign of the F98) incorporating area rule from the outset and was clearly later than the Tiger. I can't deny that the Tiger was the first to have area rule incorporated in the design from the beginning. It is also rumoured to be the first aircraft to shoot itself down by catching up with its own bullets. Would like to find some hard evidence on that one!
