I wonder why they never reported that to Lockheed? I think that it (sic) they were having so many engines problems we would have heard about it in the L-1011 support center?
I cannot answer that question, because as you imply, I never worked on the TriStar directly. My impression is that it's clearly an outstanding airplane even today.
But my experience at RJ, the numbers quoted, the conversations I had with R-R and RJ people, are just as I related.
And I suspect All Nippon was interested in having IHI or Kawasaki take on the pylon/mount/systems design for a CF6-80A conversion in collaboration with DL and NH. Maybe it was all a game of "chicken", or maybe it was genuine. But the talk was real.
