I was working in Kidsgrove (Stoke) on the UK/Irish part of a global system implementation. Most of the support people were Canadian or American.
One of the Americans picked up on what was going on and it soon spread around the project team, followed by the American's getting on the internet and frantically trying to phone home to make sure their nearest and dearest were OK.
Very upsetting and a strange situation to be in.
They all went home within 48 hours to be with their families.
What I noticed more than anything that evening, driving back up the M6 to Warrington, was how slowly and carefully the traffic was moving, very eerire. I wish the traffic was always like that, but not for that reason.
