Perhaps the SAR world needs some sort of clearing house, a bit like Chatham House, where information from credible and classified sources can be pooled without disclosing where or how it was obtained. Maybe if this had existed on March 8th we could have saved lives, if there were lives still to be saved.
No SAR goes rather well, they are proffesionel and deal with information given to them authoritys, not media and speculators like on this forum.
It is the only way to go, and yes some of that information will be wrong and will need to change there pattern as more information arises.
