I was only asking. I certainly would never have a problem with an a/c landing at LHR for the purposes of saving a life. I just have a suspicious mind when I don't have all the facts. I also like to tell the passengers why we are late (again), when there appears no good reason for a delay.
I now have more facts (thanks Gonzo) and will quietly crawl back under my stone - until presented with another situation that I cannot quite fathom. In which case I will be back on this forum to ask questions of my aviation collegues who are so adept at providing me with the answers.
Thank you
