Mission Impossible?

Another in the "scenes from my window" series.  ("Is there such a thing?" I hear you ask ... well, sort of.  You can see other examples here, here, and here.)  Today we get to marvel at three intrepid window washers scrubbing the neighbours' grimy glass.  They made me think of an outtake from Mission Impossible, or perhaps a SWAT team.  Bless 'em ... you couldn't pay me enough to dangle from a flimsy rope many stories above the hard concrete sidewalks of Boston!
