It was Nine-O-Nine, and she is a total loss. Worse yet is that seven are reported dead and one or two more might not make it. The crash crew reported that it took a couple of hours to reach the cockpit, so I'm guessing pilot and copilot didn't survive.
Pilot reported #4 engine was having problems about five minutes after takeoff, and that he needed to return to the airport. The crash occurred on landing. A couple of observers on the ground commented on a clanking noise coming from the plane as it passed by. I wonder if they lost a jug or two on #4.
Single-engine-out performance of the B-17 is pretty decent, so I am betting there were other complications that led to the crash.
We returned from a show in Madera, CA one year in Sentimental Journey and had to shut down #3 en route due to low oil pressure. We had no problems other than arriving in Mesa, AZ after dark in a plane without lights.
There were two other occasions that I am aware of when they lost jugs on an engine in flight and still made it back down safely.
