By day, a lone Lancaster would also be picked off. If you are talking at night, obviously, the 17s would have flown differently than they did during the day to keep from hitting each other. That's kind of a no brainer. As Erich pointed out, the Luftwaffe crews figured out how to counter the corkscrew, so it wasn't perfect. Do you know for a fact that the B-17 couldn't perform a corkscrew?
