Reeka, I doubt anyone will get through to Manhatten for quite some time. I am as anxious as you are. But he is unlikely to have been in the twin towers OR the trade district that early in the day - even if he is working anywhere near there, normally.
Try not to worry too much. He will be in a state of shock, and I should think the forum is the last place he will think of trying to contact. Could be, too, that all the internet connexions from there will be overwhelmed with calls.
I'm sure he is ok!
