Sharp eyes! I now see that also.
Good catch! It’s that way on the Frasca site…
Mr. Frasca was a fine gentleman, a true friend of aviation. I taught some of his sons at Southern Illinois University Aviation Technology, and would visit with them at aviation trade shows. He and I were seated together at an aviation related banquet at the university and I was able to get to know him. He shared his experiences while flying his “Felix the Cat” US Navy fighter in the movie “Midway”. He will be missed…
Now it’s fixed.
I believe that the author was referring to him as AN inventor in the flight simulator field, not as the guy who originated it. Note the in the second paragraph he is cited as being unhappy with the the then current state of the art in the field.
