Jonathan,
It is very difficult for me to contact any of our UK offices about this tragedy as I am now limited in my communications by home computer and phone.
Aon's chairman and CEO has already delivered several conference call meetings, and information is posted on our main website which I'm sure the UK offices are privy to. In addition, Aon has set up a message board web site, just like this one, where NY employees can communicate with each other and detail the whereabouts of missing persons. All Aon offices are aware of these websites.
Regards,
Matteo P.
