I was at home that morning instead of the office as I was gathering supplies and getting my talk ready for an Ag Tour event we had later that day. We were putting it on in coordination with the regional business council. Purpose was to bring in employees from just about any business in the area that had even a tangential relationship with the Ag industry.
As soon as I saw it on tv, I knew it was bad even though they kept saying it was a small plane. Called the office and told them to close the door and head to the break room with the tv. Had to go into the office as I knew the phone would be blowing up as although I had a cell phone, didn't readily give out the number.
Noon meal and my introduction was going to be at the Wisconsin Public Service (electric and gas provider)regional office, and by mid morning WPS was nervous as by that time the talk was to lock down offices from concern over possible electric grid attacks. They finally agreed to let it go forward as they were able to lock offices separately from their events room. Everyone needed an ID to enter that corresponded to pre printed name tags.
Plan was to have lunch, talks and then board busses for tours of farms and some Ag Businesses. About 75 people, and the majority of us drove our own vehicles in a big convoy as we all wanted to listen to radio and get what news we could. Nobody admitted it, but most of us were nervous about getting in a vehicle that we had no control over. Tour went over without any problems, but I'm not sure anybody learned anything.
The following day was a meeting of the County Emergency Management Team trying to figure out what if anything to do for protection of buildings and employees. For a day or two we had Sherriff deputies standing around entrances trying not to look bored. We also had Farm Services Agency and NRCS office across the hall and as they were federal, were under a different set of rules. If I recall correctly, they kept their door locked and wouldn't allow anyone in without an appointment. That ended quickly as when farmers came in and found the doors locked, they would come over to our office to use the phone.
Shortly after that spent many long days in County Emergency Management Team meetings trying to role play scenarios.
