Wrong B-26. There were two.
The first was the Martin B-26 Marauder. Also known as the Baltimore Whore for its temperamental flying qualities and short wings (no visible means of support). This was the one that coined the phrase “one a day in Tampa Bay”, and required Jimmy Doolittle to come in and teach crews how to safely fly it.
The other was the Douglass A-26 Invader, which was reclassified as a medium bomber (thus B-26) following the withdrawal of the B-26 Marauder from service following WWII. This is the one that flew in Korea and Vietnam. Where the political sensitivities of the term “Bomber” led to it being reclassified AGAIN, back to Attack (A-26)
And you've got two aircraft mixed up
Martin A=30 Baltimore was a export/lendlease only light bomber originallky designed to a French order, later supplied mainly to RAF.
Martin B-26 Marauder was the later medium bomber you are thinking about, which nobody wanted to fly.
