I found the book where I read that bit of information and then wanted to find out more. This is the best quote I could find that fit with a vast majority of what I read. (btw, thanks for the correction)
"The BELLE shot down eight enemy fighters, probably destroyed five others, and damaged at least a dozen more. She dropped more than 60 tons of bombs over Germany, France and Belgium. During her 25 missions she flew 148 hours, 50 minutes, and covered more than 20,000 combat miles. She is the only B-17 to have her own file in the Air Force Film Depository.
This gallant lady was bullet-ridden, flak damaged; on five separate occasions had engines shot out and once came back with her tail nearly shot off. There was not one major injury to the crew members."
