also if you have been out with Pop you are probably going home too late (remember you are looking at refections of the Sun; too late and the sun is too far below the horizon).
Actually did see another one the other night - out in a friend's garden drinking 9.5% Devonshire cider and we all saw one heading in a north easterly direction... don't think it was the drink... Reasonably dark out there which does help.
Like to see one of these iridium flashes...
