I first met Bill Simons at the "61 Nats. I knew that he was sick, but I did not know that he is no longer with us.
I was also at the Academy of Aeronautics contest mentioned. The date might be earlier, since I graduated from the AOA in '64 then went to St Louis University, Parks College.
Neville,
Yes, Bill also designed the P-39.
