I too was teaching a class for some Sailors on Naval Station Norfolk. I'm a Retired Navy Chief myself. We were told about the planes hitting the Towers and I really didn't think much of it as I was thinking small planes probably an accident, then were were told an airliner hit the Pentagon and the Base was being closed. I had to send the students back to their ships (the majority of the students were from USS Seattle)and as I was leaving the Base the security at the gates was like nothing I had seen in my 20 years in the Navy. We have now been attacked twice (don't forget 12-07-41) and need to find some date between those 2 dates for a National Holiday.
(I was stationed in P'cola once I loved it except for the fact that it's where I met my ex-wife)
