Ed, I’m not sure if you’re looking for a famous B-17 by name or a bomber that completed 200 bombing missions. I have not found any information on a B-17 that completed 200 missions so here are a couple made famous by their service.
The Memphis Belle, subject of several movies, was the first U,S, Army Air Forces heavy bomber to complete 25 combat missions with its crew intact. It’s at the National Museum of the United States Air Force at Wright-Patterson AFB in Dayton, Ohio under going restoration.
The Nine-O-Nine, a B-17 Flying Fortress heavy bomber of the 323rd Bomb Squadron, 91st Bomb Group, completed 140 combat missions during World War II, believed to be the Eighth Air Force record for most missions, and never lost a crewman as a casualty. After the end of hostilities in Europe, Nine-O-Nine was returned to the United States on June 8, 1945, and was consigned after the war to the RFC facility at Kingman, Arizona on December 7, 1945, and eventually scrapped. Another B-17G (Serial # 44-83575) has been returned to her wartime configuration under the auspices of the nonprofit Collings Foundation of Stow, MA and given the name "Nine-O-Nine".
The B-26 Martin Marauder was a twin engine medium bomber
During the course of its 202 bombing missions over Germany as well as the Netherlands, Belgium, and France, Flak Bait lived up to its name by being shot with over 1000 holes, returned twice on one engine and once with an engine on fire, lost its electrical system once and its hydraulic system twice, and participated in bombing missions in support of D-Day and the Battle of the Bulge. Flak Bait returned to the United States in December 1946. The front portion of the fuselage is currently on display at the Smithsonian Institution's National Air and Space Museum.
Flak Bait was assigned to the 9th Air Force, 322 Bomb Group, 449th Bomb Squadron. My father was in the same bomb group flying with the 450th Bomb Squadron.
