Some misinformation in that title, which could have been worded better by the author, plus some minor edits.
At least the article itself, if some didn't actually read it, shows that the B-26 actually had the lowest loss rate in combat compared to other similar aircraft after upgrades to the early design and much better aircrew training.
Plus, it ignores the individual B-26 named "Flak Bait" survived an impressive 207 operational missions, the highest number for any American combat aircraft in the war.
The NASM B-26B-25-MA nicknamed "Flak-Bait" (AAF serial number 41-31773) survived 207 operational missions over Europe, more than any other American aircraft during World War II (A de Havilland Mosquito B. Mk. IX bomber completed 213 missions but this aircraft was destroyed in a crash at Calgary Airport in Canada, two days after V-E Day, see NASM D. H. 98 Mosquito).
Completed in April 1943 at the Baltimore factory a crew flew it to England. The AAF assigned it to the 449th Bombardment Squadron, 322nd Bombardment Group (nicknamed the 'Annihilators'), and gave the bomber the fuselage identification codes "PN-O."
Lt. James J. Farrell of Greenwich, Connecticut, flew more missions in "Flak-Bait" than any other pilot. He named the bomber after "Flea Bait," his brother's nickname for the family dog.
