The old tower is coming down on the 28/29th Jan, starting Sat Afternoon, finishing by 1700 Sunday. Scaffolding has been removed ready for demolition. The stands surrounding the tower (5,6,9,10,11) will be closed when this takes place. This should of been done in the first place, as it would of been down in Oct/Nov. It will then be covered over. I suppose natural progression of the departure lounge down the apron is envisaged, but that won't happen for a good while I would of thought, if at all.
Not sure about the timescale for the baggage (outbound) / passenger security.
