The Air Florida crash had very little to do with the airport and a lot to do with the pilots who took off with dangerous amounts of ice/snow on the wings. Fortunately, de-icing procedures have also improved since then - in the 80s, it was possible to have a long time between deicing and takeoff; today, deicing is done at the end of the runway, shortly before lining up for takeoff.
I was in 6th grade. It was a shitty day all around -- there was a metrorail accident under the river. I was on a school bus for 4 hours while getting home in the snow. The plane hit a bridge and went into the river.
Think of what you know about DC traffic when there's a flake of snow in the air, and put an airliner crash and a metro accident on top of that.
Maybe it's not logical, but I'm still not a fan of flying through National in the winter.
