Having missed last Friday's excitement and emotion by being out of the country, I do hope that BA will give due notice of the departures of the airworthy aircraft.
That absolutely last, final take-off will be a real moment to savour, and a good reason to bring LHR to a brief but respectful halt.
I rather hope that it will be in the dark, so that we can see those four reheated Olympuses in all their full and final glory!
