Spotted...

update. it wasn't a body. it just floated past again, much closer this time. it's a mannequin/dummy thing. police helicopter and lifeguards came back and fished it out again. they were only practicing! hooray!

so that is what they were doing. in a lecture today at 12 (at aldwych), helicopter constantly flying around, lecturer goes to window, sticks his head out for a bit, closes the window "fucking single glazing". about twenty minutes later when helicopter is still buzzing "i am fucking paying for their petrol!"
