I was working construction at the time. We were doing an office building (not a high rise), and went to a convenient store for some coffee and something to eat and everyone was acting weird. I finally asked what was up and they related what had happened.That challenger disaster was definitely one of those “where were you when” moments in history. I was in Skokie Illinois being shot at by I assume a disgruntled employee.
A pharmaceutical company in Skokie was going bankrupt so our company bought them out. I was in charge of collecting all the physical company drug related confidential files (hard copy data) and clinical trial data to bring back to our headquarters in Cincinnati. While I was there overseeing the file collection and armored vehicle loading at the dock a couple of bullets wizzed past my head and took out some windows near me. Fortunately no one was hit and my security detail who were armed secured the property perimeter until the police could arrive.
I was moved to the security office with some of the building guards watching the close circuit cameras for potential shooters and there was a TV on in the room showing the Challenger launch. Watching the disaster in real time was gut wrenching and completely took our focus off of the security issue on site.
