Those are some hard videos to watch.
I'm pretty sure I saw that very Fortress fly over my home this past summer.
ETA: Last night on my way home from work, I listened to a "re-run" of a Terry Gross interview with a Tuskegee airman recorded in the mid-1990s, and the part they were at when I started on the way home was where he was talking about the terrible, helpless feeling he got when he saw a bomber take a flak round directly to the wing, the wing sheared off, and the whole plane spiraled to the ground, and he knew there was nothing he could do for them - and there was nothing the bomber crew could do for themselves. All that can be done is to watch them go into the ground.
I think watching those videos gave me a small hint of what that feeling must have been like.
