Concorde 24th October

Hey
Can anyone help me? I heard Concorde was taking off on the North runway at Heathrow on 24th October. Does anyone know if this is still the case? I am keen to get up there to see her to New York and any other flights she may be performing! Left it to the last minute, oooops! What time does she depart for JFK? 10 or 11am? Can someone please help!

thanks
