Unfortunately the OP cut-out the most incredible part of this fight....After Sarnoski is mortally wounded he starts crawling back to his gun....This is extremely crucial because the other nose mounted weapons are now inop and there is a twin engined cannon armed Japanese heavy fighter (Ki-45) boring in for a head on attack....Sarnoski levels his weapon one last

time and shreds Ki-45...Then dies at his post...OMG! how could you leave that part out? The only way it could have been more epic is if Sarnoski had hollered "Witness Me!" on his way back to his gun. The Japanese stop running "head-ons" at that point (cause they are "0 for 3") and start trying to pick the B-17 apart from angles (with no success). Joe Sarnoski saved that airplane and crew at the cost of his own life, he is an absolute BA hero that most folks don't know about.
