If anything will or has come of this disaster already it's everyone's increased awareness of the dangers of manned flight and hopefully that heightened awareness will lead to even safer skies.
Yes, that's the fortunate OR unfortunate thing about all aircraft accidents. Pilots become very conscious for the next few days/weeks/months, and then are likely to not think about it as much. I'd bet anything, pilots were looking for places to "land" after take-off following the Hudson River thing. Probably still are, but soon other things will take priority. Same with the icing; everyone will be overly conscious about it until Summer. Sad but true. Nature of the beast.
