Newton measuring the Earth at the British Library.

Long exposure fountain at the British Library. I actually managed to handhold this - 2 seconds! You can see people walking down the stairs and along the walk. I did prop my elbows and brace very carefully, though.

At the RAF museum. Look at the air intake. This aircraft did not receive much use during the war, since it came too late. It was used for towing practice targets, hence the orange underbelly to differentiate it from the targets!
