Link doesn't work anymore, but found this in my notes. It was on the Raytheon site:
September 11 Remembrance
"I will always remember what it felt like when I learned that we had four people on those planes: Peter Gay, Stan Hall, Dave Kovalcin, and Ken Waldie. We lost other colleagues as well: Herb Homer of the Defense Contract Management Agency, who was assigned to Raytheon and worked side-by-side with us for many years, and three PricewaterhouseCoopers associates working on the Raytheon account."
