Of all the 9/11 survivor stories, one of the most unbelievable belongs to two men: Brian Clark, a Canadian businessman whose office was struck by one of the planes, and Stanley Praimnath, the man whose life he saved.
On 11 September, 2001, Mr Clark was at work on the 84th floor of the World Trade Center’s South Tower. At 9:03am, Flight 175 struck floors 77 to 85 of the building, with Mr Clark’s office at the top of the impact zone.
