LT COL Mark Novak spent 27 years serving in the USAF and ANG, piloting the B-1 Lancer and KC-135, but when he retired, he didn’t stop flying. Today, with over 8,600 flying hours, he’s still racking up more flying the nearly 80 year old B-29 named “Doc” – one of only two in the world still flying after WWII.
