Heathrow Director,
Thanks for the correction. I can't believe I got it wrong after having done it for so long, but there it is, wrong. Memory is the second thing to go after retirement...

Thanks for getting back on my questions. On Q.3, no, I'm not kidding. Sometimes these things need saying even though we suspect what the answer will be. Your comments on flight data analysis and safety reporting don't surprise me at all.
