Thanks for the info about the best spotting locations. I have left instructions with She Whom Must Be Obeyed for some time that if I kick the bucket first that I want to be put to rest in the Family Plot facing east in the direction of the 17 approach at Cork rather facing in the other direction where you will see naff all.
I just have got to get in a visit to that cemetry spot near LHR. If the aeroplanes ever got boring think of the fun you would have reading the headstones. That'd be a gas day out!
