The flashmob had been called for the first saturday after the decision on the airports expansion plans and comes at the end of a packed week of protests which has already seen the domestic departures lounge of terminal three occupied by a Climate Rush dinner, a plot of land purchased by campaigners in the middle of the propose new runway and sufftragettes esculating the militancy of the campaign by smashing windows at the governments Department of Transport.

The week also saw twenty four Plane Stupid activists quietly sentenced for their part in the blockading of Standsted airport late last year.

Many more actions are expected and the Climate Camp is holding a national gathering in Oxford next weekend at which proposals to shut down Heathrow airport down completely for a day are expected to be discussed.
