The best rule of thumb is to shut the fuck up and let the people do their jobs. Don't talk to media. Don't talk to friends. Don't make cell phone calls and try to count heads. Be a fucking professional and let the Casualty Assistance Process work.
For the people that don't know, the command has to issue the PCR's so that the various regions can assign CACOs to go knock on the door of the various Next-Of-Kin. That process takes time. The command's first priority is on the search and rescue, not getting a message out. When the message finally does get out, the regions alert their CACOs and brief them on the situation and provide the name and address of the NOK. The CACO has to get dressed, get in a car, find the next of kin, and knock on the door.
This incident happened around 3:00. Do you think that process was complete at 6:35 when the original post was made? Hell no. So fucking what if it is on another web page? Giving the information additional legs in a forum like this is contributing to the problem. Don't you think that parents of SNA's and even IP's read this site? Of course they do.
There is plenty of time in the days to come to offer prayers talk about your friends that are OK, or not OK. When an incident has just happened SHUT THE FUCK UP!!!!
