9/11: Inside the President’s War Room
8.30pm, BBC One
Where Monday night’s Surviving 9/11 told the story of some of the civilians who found themselves in the midst of the September 2001 terrorist attacks, this documentary analyses 12 hours in the US presidency as the news and its aftermath unfolded. Former president George W Bush recalls hearing of the attacks at a primary school, while members of his team revisit their unpreparedness for an attack like that, as the press records their reactions.
