I was sent to cover 9/11 for Radio Five Live Many many traumatised people in the depths of despair continually stopped me in Manhattan holding pictures of their loved ones to ask, ‘have you seen my father’; ‘have you seen my sister?’ Everywhere you looked - walls, doors, hoardings, windows were covered with images of people like you and me with the word ‘MISSING’ across the top. It was deeply harrowing. I also met Todd Beamer’s widow Lisa. Todd was on United Airlines Flight 93. He was on a call out to the ground and was told that two planes had crashed into the World Trade Centre & that hijackers had taken over his flight.  He, along with other passengers & some crew, decided to try and get control of their aircraft. According to those listening on the ground, they heard Todd say to his fellow passengers, ‘Let’s roll’. The plane crashed short of its target - Washington DC.  Lisa Beamer was extraordinary. She was 5 months pregnant, and her two little boys were running around the house. She welcomed me into her home because she already knew her husband was an utterly courageous human being - and she wanted to tell the world ❤️ I will never ever forget her
