One of my neighbors (he passed away several years ago) was a waist gunner on a B-17 over Europe. He and the nose gunner combined to down an Me-262. Unfortunately, on their next mission another 262 got them.
Len and the rest of the crew managed to bail out over Holland, where they were found by the local resistance, who helped get them back to friendly lines two days later.
It's amazing to me that they even got the first one. Those things flew faster than anything they'd ever seen.
