Its the RNLB RIB on the Thames rushing to rescue someone - probably one of the Devizes to Westminster paddlers as this pic was taken on Sunday and it had to weave its way between kayakers. Fortunately I've heard no story of tragedy on the Thames so I'm guessing all systems were A-OK by the time they arrived.
And on the space theme, its the last ever Space Shuttle launch on Friday - big event!.... hmmm... Friday... big event.... that rings a bell.....
Isn't there some sort of event happening in London on Friday?
