The story I heard involved the A380 sales presentation team from Airbus. They arrived in HKG with their Powerpoints and models but before they were allowed to start, Turnbull said, "I've got someone I'd like you to meet."
In walks the engineering director who gave them a full breakdown (apposite word) on the 340-600 operation in CX. When he'd finished, Turnbull pointed out that until Airbus had sorted out the -600, there was no way they would even sniff at the 380.
The team went back to France, and within a few days a very high powered engineering team arrived to help on the -600 reliability problems.
Apparently happened a couple or three years ago
