He spearheaded a range of amazing projects to include a helmet with infrared night vision like in Blue Thunder, the predator and global hawk which were the very first unmanned drone planes to exist, and Action Machine his dream business.
He spent many years of his life touching the lives of those around him and building friendships.

What a great man John was, and still is! I worked beside him on many exciting projects for over 21 years. I learned what a true, dedicated friend should be by associating with John. I know of no one who didn't love and respect him. I'm thankful that I was able to meet with him, and have a nice talk with him just a few days before his passing. He will truly be missed by all of us. Good bye for now John. I'll see you before too long.

John and I met at Sperry in 1975. We became good friends and helped each other when it was needed. One of the things we did for the last 30 years was to call each other every morning. Just to see what each other's day was going to be like. I will miss our calls and John very much. It is sad to loose a good friend like John,
