Geez... it took them 4 whole hours??? I can't believe they were so inconsiderate as to leave you waiting like that...
perhaps they needed time to notify next-of-kin, possibly to implement emergency procedures, and to do hundreds of other things that needed doing that were FAR more important than to let everyone know IMMEDIATELY that there was a mishap...
I mean, come on man, use your head - they obviously had priorities, and quite frankly I'd be MORE bothered if they started press conferences while the debris was still falling...
