Sorry to report everyone but Ol' Jack passed away. His daughter created a facebook group dedicated to him
https://www.facebook.com/oljacksplanetarium. I went to Oakton High School after he retired but I took astronomy and in the back of the planetarium room the painting of Ol' Jack as the sun was still there. I saw him at the planetarium multiple times when I was in Elementary School. His presentations are memories I will have forever. Thanks Ol' Jack.
