Dozing somewhat at 3am this Sunday morning, there's a very distant turboprop droning coming over London, so intrigued enough to get up and have a look, turned out to be an Israeli Air Force Hercules, Jerusalem (or near) to Prestwick, passing overhead at altitude. Half an hour later there's another such noise, go downstairs again, it's a second one on the same track. Presumably off across the Atlantic.
Mrs W not notably amused to be informed of their progress ...
