We need the dispatch recordings.
Three (!!!) in one night, fairly close timing all together. [”Three means war” and declaration of ‘religion of war, not religion of peace’ just the other day.] This is getting more and more ‘headline news worthy’.
People would have been too busy responding to the derailment, and not reporting seeing any suspicious lurking personnel.
