Nine out of 10 British adults remember where they were when they learned of the September 11 2001 terror attacks in the United States, a survey has shown.
The poll, conducted by YouGov to mark the 10-year anniversary of 9/11, revealed 91 per cent of adults are able to recall what they were doing when the planes hit the Twin Towers.
As an indication of how the attacks have been imprinted on people's memories compared to other events, only 68 per cent of British adults can remember what they were doing when they learned of the July 7 2005 attacks on London's transport network that killed 56 people.
The survey also revealed that 84 per cent of people remember where they were when Princess Diana died, 25 per cent when Margaret Thatcher resigned as prime minister, 22 per cent when Nelson Mandela was released from prison and 29 per cent when the Berlin Wall fell.
YouGov polled 1,948 adults between the 6th and 7th September 2011.
But while memories of 9/11 are fresh in the minds of the majority of British adults, a separate poll has revealed that hardly any Afghan men know of the attacks.
According to a survey 92 per cent of 15- to 30-year-old men in the south of Afghanistan did not know about "this event which the foreigners call 9/11" even after having an explanation read to them.
The results are particularly surprising given the presence of US, British and other Nato troops in Afghanistan came as a direct result of the attacks in 2001.
