Sad news indeed. To those only around the past few years, Jack was a Operating Steward for many years. He also used to share a race car with his brother Hal Pringle.
Full of personality, and never short of an opinion, Jack was one of those guy's that could make you laugh, make you think, and most of all , gave a damn.
R.I.P. Jack. Rumor has it ,heaven is full of Corvettes.
