Was flying along on AP enroute a few minutes after resuming a autosaved flight from the day before, was not currently interacting with xplane at all, suddenly screen went red like a negative G red out and xplane crashed to desktop. Not sure if 650 log has anything relevant, I reloaded xplane and resumed the autosaved flight again before saving it off, the log.txt was saved off.
