Sorry Folks - having left LHR in 2000 I am not up to date. Certainly when Bill Clinton arrived for the Good Friday Agreement LHR was used - I was on duty the morning AF1 departed for Belfast and again when it arrived back the following morning. As I said above just another movement for LHR, London Control etc - as for the associated helicopters, a nightmare! Best to 'throw a sickie' rather that risk your licence with them!
