Having some experience at this, you will ALWAYS have someone complaining about the family response...
It is FAR BETTER today than it used to be, mainly because of situations following the USAir/Pittsburgh, and TWA 800 debacles...
I am following the story later...now they are saying nothing about the cause of this crash which makes me suspicious.
Yeah, there is no easy way. They are in shock. I would expect confusion and anger.
It is difficult enough to deal with the sudden loss of a loved one. Even more difficult also having to wait for information. I fully believe that local authorities, medical response, airport response, etc. responded as well as could be under this stressful situation.
