Condolence: Wishing strength, courage and time to heal to Jon's grieving relatives, especially to his brother James' family.

Condolence: Dear Lisa Ann and familiy Thinking of you a lot in these sad days of taking leave of your beloved brother and uncle ( not sure if this expression is right in english). My deepest sympathy. Love and Kisses from Switzerland, Mireille

Condolence: We were so saddened to hear about Jon's passing. When we think of Jon we remember the many Christmases we celebrated together. It meant a lot to us to spend this special day with family and friends like Jon. We are consoled in knowing that he is at peace with our Lord. We will miss you Jon.

Condolence: My husband Craig and Jon were good friends since childhood. I was blessed to be able to meet the man behind all the stories when we visited Texas in 2017. Jon took us to the NASA Space Center, and treated us the best darn barbecue I’ve ever had. But my favorite part was when we picked him up to go NASA. Craig had told him I liked Barry Manilow. Jon came out of his house, got in the back seat, and handed me a Manilow CD. Not many men would do that. I liked him immediately. Please accept our condolences, and know that we are grieving with you at this time.

Condolence: Jon, I knew when I would see you at events or when you would call that I could count on you to tease me. Now you'll have a new group of people to tease! I'll miss not seeing you or talking to you. You were a nice person. Since hearing that you were gone I've had to stop myself from adding you to my forwarding list of emails. I counted you as a friend. My sympathy goes to your family. You left at a young age. Now you are no longer in pain. We will miss you Jon.

Condolence: It`s not a party yet! You`ve been a friend for a long time, since we were both Space City Ski Club members back in the 80`s. And all the years since then, we have been at the same events. You always said, "It`s a party now." when I showed up. I loved it. Well, I hope to be partying with you up in heaven one of these days. RIP Jon
