Dave - you are correct. It was the redesign of the YF-102 to the F-102A that resulted in the Whitcomb Area Rule change to fuselage because of disappointing speed performance of the YF-102.
The F-102B was a further and major redesign of the A and became the basis for the F-106 because the B was so significantly different.
Er, hello? Who was correct?
no offence Dave, you too
