Making this call does what to help the situation? Last thing on a long list of requirements.
Agreed that the Fitzgerald's crew had their hands full with damage control and medical/search emergencies. Also, it has been reported that the Fitz' radio room was put out of commission by the damage.
The benefit to the situation would have been clarification of the time (and location) of collision. The long-delayed report by the crew of the ACX Crystal was so late that, for most of a day, the reported position of the collision was after the Crystal had done all her "Crazy Ivan" maneuvering. Worst of all, from that point, she accelerated away -- looking like a "hit and run" without stopping to render aid. That led to much speculation re a deliberate attack -- which confused even me.
Finally -- sorting out the time put the collision at the point where the Crystal began her wild maneuvers -- and clearly showed that she did return (albeit nearly an hour late) to the scene of the crash to offer aid and radio a (delayed) report.
A timely report by the Fitzgerald (with an accurate"Zulu" [UTM] time of collision) instead of "local time", as (belatedly) reported -- would have clarified matters considerably.
