The maintenance report on 'Sweet Ada' that stated they removed 116 lbs of shrapnel about says it all. You have to wonder how the crew even lived through that!
one of the local parts suppliers i deal with, i tend to bs with the counter guys a lot. as it turns out, jim's dad was a bombardier on a b17 near the end of the war. i thinnk he flew 7 or 8 missions.
he came to my CAP squadron, to talk to the kids.....all of us..

, but mainly the young kids. he told them of his training, how they got to their base, etc.
then he started telling them of a mission over italy(i think it was italy), where the flak was particularly heavy on the way in and out.
he was amazed that there weren't too many fighters, even when they weren't in the flak. as he was telling them of the malfunctioning chin turret, he reached into his pocket, and pulls out a small bundle...looks like a reg. he unwraps it carefully, and holds up a piece of shrapnel.
it couldn't have been more than 2" long, and not a full inch wide at any one point. there was nowhere to hold it without touching a very sharp edge. judging by it's size, one would only expect it to have weighed an ounce or 2.
friggin thing weighed much more than it looked like. then as it was being passed around, he explained that the malfunctioning chin turret was caused by this shrapnel. said turret also saved his life, according to the crew chief of the plane.
the guy came there in his dress uniform from the 40's.
one of the coolest guys any of us ever met.
