The thing that sticks with me was a few days after 9/11 was when I was at the station waiting for my train to London and I saw my mate Rob who worked for a company called Risk Waters.
He looked in a daze and I asked him if he was alright. He said he was totally shook up from 9/11. He then told me that he was on the phone to his US colleague who was on the 110th floor when one of the planes hit.
He just said “my mate said I think a bomb has gone off, the building has just shook, I’ll call you back”.
He called him back 15 minutes later telling him he’d loved working with him and that he should look after his family as he didn’t think he’d make it out.
my mate said the phone line cut out just as he said that.
He then watched on tv 30 minutes later the tower he was in come down.
