Bart entered the Air Force during a golden age of jet aviation. It was a pilot's paradise. New and exciting jets were coming out and the country needed many new pilots to fly them. His first military aircraft was the T-6 Texan. A trainer developed in WWII, it remained in service into the 1950s.
Bart's first jet was the Lockheed T-33 Shooting Star, a trainer.
(He is shown with it in the photo at the top of this page.)
After the T-33, Bart went on to train in the Republic F-84 Thunderjet,
a fighter-bomber (but mostly bomber)
Then Bart went to his first real jet fighter, the F-86 Sabre.
He flew these in Korea but arrived too late to see combat action.
After returning from Korea Bart joined the 1708th Ferrying Wing. Pilots in this unit were qualified (to ferry) many different aircraft , usually multiple propeller planes and two or three jet aircraft. The North American F-100 Super Sabre was one of these.
"Ferry" means flying an aircraft from one base to another. A ferry pilot may, or may not have been qualified to fly that aircraft in combat operations. Bart was only trained to ferry the F-100.
Here are some other photos and artwork of the Super Sabre:
The USAF Thunderbirds flew the F-100C from 1956 to 1969
