Considered my excuse because I couldn't face climbing through Tower Blocks again. They let me wait at the top of Knossus pitch to take out a tackle sack. I derigged the entrance pitch. We carried down a huge load at the hottest part of the day. Fighter jets tore the sky overhead. Caught sight of one. It was a delta-wing, so was probably one of those 'stealth' bombers on its way to liberate the oil in Libya.
