Then perhaps you shouldnt have said

Sputnik was the lead in to a dead-in technology.

Quote the whole sentence, Kevin.
"Compared to the changes that followed from the Wrights' flights,
Sputnik was the lead in to a dead-in technology."

That
was a comparative phrase between the advancement in and change
caused by the two lines of progress (manned flight vs space flight)
and their respective beginnings.

It was also demonstrably wrong.

I disagree.
