After a meeting in London i decided to extend my stay for one day. I use it in London Heathrow airport in a cold and cloudy day. The first day i took pictures of planes the last hours of the day before it gets dark. The second day I walked to Myrtle Avenue where a couple of other plane spotter stood and took pictures. London Heathrow is is a very good airport if you like heavy planes, there are though som boring times were alle the BA feeder trafic is comming in, but that I think is normal for all the big international airports.
