First, about that horrible  Reagan National Airport air collision  between an American Airlines flight holding 64 passengers and crew from Kansas and an Army helicopter manned by three.  There were no survivors. I still remember a  similar incident on 13January1982  when I was working in the U.S. Senate.  On a cold and snowy day in the later afternoon, Air Florida 90 left Washington National Airport, but crashed soon after takeoff into the 14th Street Bridge, killing 78.  Five on the flight survived, but four motorists on the bridge died.  An unrelated accident shut down one of the Metro lines at around the same time, and it took me till midnight to get home.
