I'm really sad today !
On the Tristar one day we had two engines with serious vibs on both channels. Dave said, "this requires some serious immediate action, old boy", so he reached up for the C/A call bell and ordered tea all around - we never did shut anything down... and, of course, all was well.
He looked after all of the new young Captains like myself - I'll never forget him - I think I'm going to have a quiet day today
