I was a BTL person for 8 years between 1976 and 1984. During that time
there was a spelling corrector that was better than anything I see today.
There was a concept of "spelling distance" that corrected a whole bunch of
stuff that even today cannot be corrected.

Who in that era worked on spelling correction at BTL. I was at Columbus BTL
(1976-1979) and Whippany BTL (1979-1984).

Who ever did that stuff should patent it and sell it. Today there is
nothing like it.
