I'm 1m south east of LHR - can see the planes once they get to 400m or so - theres a strip of chunky mackerelish stuff, and big clouds way off to north east - will report back one mutts walked, can get a better view off to the north from the park, view here obstructed by houses somewhat in that direction - a fair breeze has got up now, enough to take the humidity down a touch, thank god!
