My late Father was a bombardier in a B-24 Liberator in the Pacific Theater. He said the plane was a cramped death trap and it wasn’t until the 1970s that he dared set foot in a plane of any kind.
The B-24 was a difficult plane to ingress/egress on the ground, let alone in combat/battle damage conditions.
I saw some European combat footage, and I think it was a B-24 that was at the back in a lower formation. A bomber above let loose and a bomb struct the stabilizer, shearing it off. The plane immediately nosedived. I doubt anybody could have gotten out.
