For the very first time, Sir Richard Dearlove - the MI6 chief during 9/11 - has told the full story of the RAF plane that crossed the Atlantic and flew over the burning wreckage of the Twin Towers while US airspace remained closed.
In an exclusive interview with the new Defence Insider app from Sky News, Sir Richard tells Professor Michael Clarke what he saw on that flight - and his subsequent meetings with US intelligence as they identified Osama bin Laden as the ultimate mastermind of the attacks.
Watch the full interview now with a free trial for more on:
- How the UK knew a US "overreaction" was inevitable - and how they responded
- A "fundamental" difference of opinion between the UK and US on the role of another world leader
- A different perspective on why Tony Blair joined the war on Iraq
- How US intelligence views their UK counterparts today
