Had a look at Tate Britain where Fiona Banner had the installation with the Harrier and Jaguar jets. Also saw the Turner paintings.

Later had a quick look at the Golden Hind, the replica built in 1973 of Sir Francis Drake's ship that repetated his circumnavigation of the globe. Arrived a bit late for the tour inside but as it was moored practically on the street, there wasn't much left to see :).
