Creak and groan ? Don't like the engine sounds ? Trying flying out of Mpls on NW's DC-10s. They have a grunt that's all their own.
Don't blame the messenger, man! I'm not saying these things bother me or even if I have heard them,, only that I have had these complaints made to me numerous times. As for the DC-10, I haven't been on one in years. I didn't even know that any were still flying.
